Dear gap forum:
                          I have GAP 4r2 running on linux RedHat 6.2 on a
Pentium 3 PC with 512MB of RAM and 1 GB of swap memory, and I am trying to
compute the lattice of subgroups of the  group (degree 12): (2,4),
(2,12,10,8,6,4), (9,11),(3,,5,7,11),(1,3,5,7,9,11).

GAP is taking a long time (more than 950 min) to compute this and still has
not finished. I am worried since previously I computed the lattice of
subgroups of a related group of same order and it did not take more than 50
min to do it. For the unfinished computation, when I started GAP I gave it
the following memory parameters: -m 500m -o 1000m.
My question is: Could it be that GAP has fallen into an infinite loop?

Thanks for your attention and help regarding this matter.
