I wish to determine the size of many (3*12^4) groups. These groups
are given by generators (4 generators) and relations (16 relations).
It was very easy to program it, and I was surprised to see that all
the groups had order 2. I suspected an error, and found it in Chapter
21: you can not change the generators of a group! I had fixed one
group and just kept changing its generators.
I do not see how to get around this problem, except by writing
an AWK program to write 3*12^4 gap programs, and execute them, but
there must be a better way.
