N. Gavioli, SUBGROUPS OF FINITE SOLUBLE GROUPS INDUCING THE SAME PERMUTATION CHARACTER, Transactions of the American Mathematical Society, 349(7), 1997, pp. 2969-2980
In this paper there are found necessary and sufficient conditions that
a pair of solvable finite groups, say G and K, must satisfy for the e
xistence of a solvable finite group L containing two isomorphic copies
of G and H inducing the same permutation character. Also a constructi
on of L is given as an iterated wreath product, with respect to their
actions on their natural modules, of finite one-dimensional affine gro
ups.
