Dear forum,
The group 3.M_{22}:2 has a rank-9 imprimitive permutation representation of
degree 990. (This is the full automorphism group of the distance-transitive
Ivanov-Ivanov-Faradjev graph.) I would like to construct this group in GAP.
The www ATLAS gives a matrix representation of this group in characteristic 2;
however, applying "IsomorphismPermGroup" to this matrix group gives a group of
degree 693.
Does anyone have a suggestion for how to obtain the degree 990 representation?
Thanks,
Robert Bailey.
