-
- What are the best/simplest to use/most powerful software packages
- for `doing' group theory??
-
- I don't really know if they are best/simplest, but apart from several
- standalone programs implementing a single algorithm there are only two
- general purpose group theory systems available. One is Cayley and the
- other one is GAP.
-
- I don't think I am in a position to compare those two, being one of the
- principal authors of GAP. In many regards they are quite similar, in
- other regards they are very different. You should look for yourself.
-
- He continues:
-
- I have access to Maple, but am interested in other programs if they
- exceed Maple in convenience and/or power.
-
- Both do. For group theory computations that is.
-
- He continues:
-
- I am primarily interested in ftp-available programs, but commercial
- programs can also be of interest.
-
- GAP is freely available. 'ftp' to one of the following servers
-
- 'samson.math.rwth-aachen.de':
- Lehrstuhl D fur Mathematik, RWTH Aachen, Germany (137.226.152.6).

-
- and *first* get the file 'pub/gap/README', which will give you further
- instructions.
-
- Cayley is not free. I don't know the exact price, which depents on
- whether you want a single workstation license or a network wide license,
- whether you are an educational institution, etc.; but it is on the order
- of magnitude of US$1000. For more information contact:
