Dave Posted January 5, 2007 Share Posted January 5, 2007 You'll be wanting to use Sylow's theorem for this. It's such an easy application that I don't really want to do it for you. Link to comment Share on other sites More sharing options...
Tom Mattson Posted May 18, 2007 Share Posted May 18, 2007 You don't even need the full blown Sylow theorems. You just need Lagrange's theorem. Link to comment Share on other sites More sharing options...
