I would like to know how to save(to disk) the groups that GAP creates so that I
do not have to wait for GAP to redo any lengthy computations everytime I start
up the program.

What I've found that works is to take a look at the PrintRec function and the
PrintTo function and write a PrintRecTo function by replacing the Print
function with the PrintTo function. You will have to adjust the file so
when it is read in the record will be set equal to some variable, and the
.operations section should be set equal to the proper set of operations. i.e.
GraphOps. This can really use up disk space if you have large groups however.

Hope this helps,
