Dec 31, 2009 at 16:22 | comment | added | David E Speyer | Pete is also implicitly using the odd order theorem, to know that the nonabelian simple factor cannot be odd. | |
Dec 31, 2009 at 14:47 | comment | added | Pete L. Clark | A group is nonsolvable iff it has at least one nonabelian simple group as a composition factor. Moreover, if G is a finite nonabelian simple group of order a, then for all positive integers x, ax is the order of a nonsolvable group: G x Z_x. | |
Dec 31, 2009 at 14:43 | comment | added | Martin Brandenburg | how do you arrive at simple groups? | |
Dec 31, 2009 at 14:09 | comment | added | Pete L. Clark | That's right -- it's an elementary exercise that a simple group cannot have order twice an odd number: a permutation representation argument shows that a group of order 2 mod 4 has a subgroup of index 2. | |
