Dear Forum,

I have a large group, a quotient of an infinite group on five
generators. I have a permutation representation of it on 50 points,
and would like to find a presentation for it.

The order of the group is 943718400 = 2^17 . 7200. I know the
presentation of the (non-normal) subgroup of order 7200 generated
by 4 of the generators. I'm using the two-stage algorithm provided
in GAP4r2, but so far it's taken 3 days on a Pentium 550 under

Any advice on how to tackle this kind of problem more efficiently?

Yours, Mike H...
