| Apr 29, 2010 at 15:54 | comment | added | Kevin Buzzard | Here's a question of a vaguely similar nature. Say a group $G$ is indecomposable if it can't be written $G=H\times K$ with $H$ and $K$ subgroups, neither of them the trivial group. Can you find a group $G$ with $$G\cong A\times B\times C\cong D\times E$$ with $A,B,C,D,E$ all indecomposable? | |
