Needs more focus | |

| Jun 13, 2016 at 11:44 | comment | added | Sushil | although I had asked for some kind of classification or well known theorems like en.wikipedia.org/wiki/Schur-Zassenhaus_theorem. But I just want clarification on your comment. If G isomorphic to semidirect product of H and G/H, Isomorphic image of {e}*G/H will be required subspace, right? | |
