From Wikipedia : Prototropy is the most common form of tautomerism and refers to the relocation of a hydrogen atom. on these Images you san see the four(4) tautomeric forms of a <TRIPLE-Base> !!!... FIRST !!!... IF you look only at ONE "Base" !!!... You can see the inside Hydrogens to move (Left/Right) from the one Nitrogen-atom to the near Nitrogen-atom !!!... of the same "Base" !!!... and that ist "Prototropy" !!!... SECOND !!!... IF you look now to the three(3) "Bases" !!!... Between two(2) Bases !!!... You have two(2) Hydrogens !!!... which can move !!!... BUT now !!!... they don't need to move (Left/Right) !!!... But they can move (up/down) from the one Base to the other ... the one Hydrogen !!!... and the opposite direction the other Hydrogen !!!... of the second Base !!!... and that is "Double-Prototropy" !!!... The Hydrogens which moves !!!... have to chance places form a "simple-Bond" to a "Hydrogen-Bond" !!!...

This are the four(4) "tautomeric" forms !!!... of a <TRIPLE-Base> !!!... and THIS is an IMAGE !!!... of My two(2) <TRIPLE-Bases> !!!... with OUR two(2) <DOUBLE-Bases> to compare them with each other !!!... and THIS is My <TRIPLE-D.N.A.-Helix> !!!... with the two(2) <TRIPLE-Bases> "inside" !!!... ( and our <DOUBLE-D.N.A.-Helix> with the two(2) <DOUBLE-Bases> !!!... ) My <TRIPLE-D.N.A.-Helix> !!!... is ONLY a theoretical speculation !!!... for an "Alien" possible D.N.A. !!!... The "same" !!!... You can "Imagine" !!!... with My six(6)fold D.N.A.-Bases !!!... This is only S.F.B. = "Science Fiction Biology" !!!...

I have made with "Molecular Models" ... three(3) Molecules !!!... which can unite together to ONE UNIT !!!... with "Hydrogen Bonds" !!!... First !!!... with my "cheap" and "small" Molecular Models !!!... The GREY-Bonds are (-) "simple Bonds" !!!... and the RED-Bonds are (=) "double Bonds" !!!... On the YELLOW-Bonds are the "tautomeric Hydrogens" which can move to the beside BLUE-Nitrogen and change position !!!... Second !!!... with my "Ball & Stick" Molecular Models !!!... ( FAA≡BBC≡DCE≡FAA ) & ( LDG≡HEI≡JFK≡LDG ) You can see ... the GREY ... (-)simple ... and (=)double Bonds!!!... On the PURPLE-Bonds are the "tautomeric Hydrogens" !!!... ( and the YELLOW-atom is ... a charged BLUE-Nitrogen(N+) atom !!! ) Third !!!... with my "Spacefilling" Molecular Models !!!... You cannot see the "Bonds" between the atoms !!!... but you can see !!!... the "Space" of each of the three(3) Molecules !!!... I have changed the 4 WHITE-Hydrogens !!!... with 4 WHITE-GREEN "Fluorine-atoms" !!!... to "mark" the "tautomeric Hydrogens" !!!... and ... on the small-squares !!!... you can see the "differences" !!!... between the atoms !!!... of the three(3) Molecules !!!... from the Left-triplet to the Right-triplet !!!...

This is the normal 3*3*3 Rubic Cube ... and this is a LEGO 3*3*3 Cube found by amazon !!!... and this is the 3*3*3 Lego-Cube for Blind people !!!... WHITE = 0 and BLACK = 4 RED =1 and GREEN = 3 YELLOW =2 and BLUE = 2

THANK You for your comment !!!... I am only asking if a "Fullerite C24" can be done by Natur (or by Humans) having in Mind that the "Cubic Fullerite C24" is made by scientists !!!... ( Is there some reason that prevent the construction of "Fullerite C24" ???... ) https://link.springer.com/article/10.1134/1.1649442

This is the "Cubic Fullerite C24" made from "Cubes" and "Fullerenes C24" which have the shape of "Truncated Octahedrons" !!!... Could "Theoretically" exist a solid "Fullerite C24" with only Space Filling "Truncated Octahedrons" ???... Why NOT ???...

This "Triple DNA Helix" on Earth ... is NOT a "real" Triple-Helix !!!... because the "Third-Base" has "Hydrogen Bonds" only with the one of the other two Bases of the "Double-Helix" !!!...

In the "DOUBLE Helix DNA" there is NO "Free Space" inside it !!!... In my second version of the "TRIPLE-Bases" ... that I call "Boomerang-DNA"... there is "Free Space" inside the 3 Bases and other small Molecules could Bind there and then prevent the binding of the 3 Bases together !!!...

Which one do you like ???...

Both "TRIPLE-Bases" are beautiful !!!... but for a DNA-Helix I choose the one on the right as more possible !!!...

Alien-1 : "Why do the people on Earth believe ... that there is NO "Triple DNA Helix" ???..." Alien-2 : "Because they think only "twice" !!!... "

The 2 "TRIPLE-Bases" = UP & DOWN (left) with their tautomeric "Triple Bases" = (right)

I have NOT a GOOD "Molecular Drawing Software" !!!...

This is the END of my work with the "Triple DNA Bases" !!!... Someone will like it ... some other not !!!... It would be very kind if you write me your true and scientific opinion !!!... Remember that all the inventions ... startet with one Hypothesis or one Theory !!!... Scientists have made other smaller Molecules that NOT exist in Natur !!!... With "Chemical Synthetic Biology" my "Triple-Bases" and my "Triple DNA Helix" can be made !!!... Have a nice Day - EVERY Day of your Life !!!... Kni - Greece

The Bases (1-4) & (2-5) & (3-6) have the same "Molecular Formula" !!!... ( only the position of some atoms changes !!!... )

This is the START position with opposite "Hydrogen Bonds" !!!... And these 2 Images show into (YELLOW-Circles) the differences between the 6 Bases !!!...

Inside the "Free Space" of these "Triple-Bases" of the "Boomerang-DNA" could other Molecules prevent the binding of the 3 Bases !!!...

By only "comparing" it with my First Design !!!... By the "Boomerang" version ... there is too much free space inside the "Triple-Bases" !!!...

This is another IDEA of 2 Triple-Bases DNA ... which I call "Boomerang-DNA" !!!... But it is too LARGE !!!... to be useful ...

The Left-Triplet (YELLOW) has a Carbon(C) atom more - The Right-Triplet (BLUE) has a Nitrogen(N) atom more.

"Theoretical" my Idea for 2 "Triple-Bases" of ( my ) "Triple DNA Helix" ... is possible !!!... To test my Idea there is only one way !!!... to make them with "Chemical Synthetic Biology" in a Laboratory !!!... or ... to wait ... until "Aliens" with my "Triple DNA Helix" visit our Earth !!!... I write always my "Triple DNA Helix" because on Earth exist a ( 2+1=3 Triple Helix ) which is a normal "Double DNA Helix" with the addition of one Helix !!!... If we make my Triple DNA Helix ... we could learn something about the DNA !!!...

Until now there is NO evidence that my 2 "Triple-Bases" or my "TRIPLE Helix DNA" exist in Natur !!!... It exist only in my Mind !!!... (sorry !!!...) And the Question is NOT if Life could choose only one "orientation" of the "Double-Bases" !!!... The Question is ... HOW could Life make it ???...

This is our "DOUBLE Helix DNA" on Earth !!!... From the "theoretical" possible 6 pairs with 12 Bases ... it has only 2 pairs with 4 Bases !!!.. On other extraterrestial Planets with Life ... they will have probably a "Double Helix DNA" with 1-6 pairs of DNA-Bases !!!... My IDEA of a "TRIPLE Helix DNA" is only "theoretical" and "hypothetical" !!!... But with "Chemical Synthetic Biology" ... we could make my 2 "Triple-Bases" and a "TRIPLE Helix DNA" to see if it is possible to exist !!!... ( Life finds always a way to make incredible things !!!... )

The NAMES of my 6 "Double-Bases": FAA = Federal Aviation Administration BBC = British Broadcasting Corporation DCE = Data Center Ethernet LDG = Latitudinal Diversity Gradient HEI = Hawaiian Electric Industries JFK = John Fitzgerald Kennedy

All the possible "combinations" to form a "Triple-Base" !!!...
