Subgroups forced by quotients of symmetric groups
Subgroups forced by quotients of symmetric groups
For finite groups , write when every finite group having a quotient isomorphic to also has a subgroup isomorphic to . The symmetric-group quotient-to-subgroup conjecture. For every positive integer , there exists a positive integer such that
This conjecture asks whether sufficiently large symmetric quotients force smaller symmetric subgroups in arbitrary finite extensions. The paper notes that no examples were known with a non-abelian group on the subgroup side and presents this as a conjectural counterpoint; it remains open.
