Let $G$ and $H$ be two finite non-isomorphic groups in GAP.
The GAP command
IsomorphismPermGroup
can compute permutation groups isomorphic to $G$ and other permutation groups isomorphic to $H$.
Suppose that $G$ and $H$ have isomorphic defect groups $D_G \cong D_H$.
Question:
Is there a way to compute isomorphic permutations groups $\hat{H}$ of $H$ and $\hat{G}$ of $G$ with GAP such that $D_\hat{G}=D_\hat{H}$ are really the same permutation group with the same elements, and not only isomorphic?
Thank you very much for the help.
