Oct 20, 2012 at 20:34 | comment | added | Will Sawin | Presumably, what you are looking for is a relatively elegant axiom system in which the proof of the classification of finite simple sporadic groups is possible and that proof approximates the standard proof of the classification in ZFC. I have no idea if such a thing is possible. | |
Oct 20, 2012 at 20:31 | comment | added | Will Sawin | The key problem seems to me that, naively, finite and simple are second-order properties, whereas sporadic naively might mean "not part of a nice infinite family of finite simple groups" or "not a cyclic group, an alternating group, or a Chevalley group" or something else that's hard to axiomatize elegantly. There are indeed many first-order axiom systems whose only models are the 26 finite simple sporadic groups, but by completeness they are all equivalent. | |
