The memory limit in GAP is what your machine can cope with -- i.e. I would put it at roughly 3/4 of physical memory - the rest is often used by the operating system and the machine crawls down to an unusable speed if you use more. (and of course limited to <4GB if GAP is compiled for 32bit). GAP itself does not limit the process size and on a modern machine you thus should easily have a magnitude of memory more available than what the student version lets you do.
As a safety device for acidentally huge GAP jobs taking over a machine, GAP will initially issue an Error message ``out of memory'' when processes use more then 256MB, you can simply type return; at this point and GAP will continue with a higher limit (or you could start with the -o command line option to raise the limit a priori). If you start GAP with the -g command line option you will get intermediate output about memory used.
