I tested GAP on my system with:

GAP 4.8.6, 12-Nov-2016, build of 2016-12-21 01:57:40 (UTC)
Architecture: x86_64-pc-linux-gnu-x86_64-pc-linux-gnu-gcc-default64)

By limiting memory with -K I was able to do the full calculation in 647
milliseconds with only 160 megabytes of memory.  I tested with 128
megabytes and GAP hit the memory limit.

Presumably 64 bit GAP uses more memory than 32bit GAP (because of
pointer size differences).  If you're using a 32bit build it wouldn't
surprise me if you could do the calculation in only 128M for the
workspace.

In any case, this calculation is tiny.  Just give GAP more memory.
