โœฆ Synopsis


Let G be a finite group and H be an operator group of G. Suppose that

that G is solvable, if H acts non-trivially on G but acts trivially on all proper H-invariant subgroups in an appropriately chosen class subgroups. The detailed structure of such a group G is determined.

In this paper G denotes a finite group. As is well known, the converse of Lagrange's theorem in group theory does not hold. That is, given a finite group G of order n, and given a divisor d of n, G need not have a subgroup of order d. Indeed, a celebrated theorem of P. Hall states that it suffices t
