Investigating the subgroup structure of $SL_{3}(\mathbb{Z}/4\mathbb{Z})$

Question

I'm trying to investigate the subgroups of $SL_{3}(\mathbb{Z}/4\mathbb{Z})$ through the use of GAP. However, whenever I try using LatticeSubgroups or ConjugacyClassesSubgroups, I either get a message telling me i've ran out of RAM, or it says that no method is know. I assume this is because of $SL_{3}(\mathbb{Z}/4\mathbb{Z})$'s order( I believe 43008?) is there anyway of giving more memory to gap to allow it to do calculations for long(i have 16gb so i have enough to spare) and/or a way to get it to know a method for dealing with groups of this size

thanks in advance

Answer 1

You can use the -o option, e.g.

gap -o 4G
