help with a group question please


Recommended Posts

They really asked you to write out the group table? What level course is this?

In my semigroups course I had a question the other week where I had to draw the multiplication table for the semigroup of just 2 elements...I guess at all levels there can be some need to use the tables of the simplest groups etc.

It's a finite subset sof the complex numbers closed under multiplication and possessing inverses and identity, hence it is an abelian group. They really asked you to write out the group table? What level course is this?

 

this is a 1st year course, although to me it seems so difficult
