| Aug 1, 2013 at 6:04 | comment | added | Dan Ramras | The published paper has more info than what was in the thesis, I think (or at least better proofs). The arXiv version is probably good enough: arXiv:math/0210001. Probably anything I know (knew?) about this is in there... | |
| Jul 30, 2013 at 0:46 | comment | added | Benjamin Steinberg | math.cornell.edu/~kbrown/ramras.pdf discusses examples of simple groups which give wedges of circles, so free groups. It is conjectured that finite groups give only wedges of spheres of possibly different dimensions. | |

| Jul 30, 2013 at 0:33 | comment | added | Benjamin Steinberg | In the paper the OP linked it points out that it is known that for a finite group you get something shellable (which implies homotopy equivalent to a wedge of spheres) iff the group is solvable. | |
