The Feit–Thompson theorem states that noncyclic groups with this property must have even order or be infinite. For 10 points each:
[10m] Name this property possessed by the 26 sporadic groups. The only normal subgroups of groups with this property are trivial or the entire group.
ANSWER: simple groups [accept finite simple groups]
[10e] Abelian groups that are simple must be cyclic because their binary operation has this property. Matrix multiplication does not have this property.
ANSWER: commutativity [accept commutative]
[10h] A theorem named for this mathematician implies that the order of any finite non-abelian simple group must be divisible by three primes. A free Z-module called this mathematician’s “ring” encodes how a finite group can act on finite sets.
