A transitive permutation group is said to be semiprimitive if each of its normal subgroups is either semiregular or transitive. The class of semiprimitive groups properly contains primitive …
Let T be a finite simple group. For a finite group G, we determine an upper bound on the number cT (G) of composition factors of G that are isomorphic to T. We consider this problem …
