Hi,
Just to mention few incompatibilities with two nice different objects
in Sage: the Permutation and the PermutationGroupElement. I can
understand that we need to distinguish the two objects (not so well),
is it projected to have a fusion and if not why ? compatibility
between them ? Which one
2) Is it consistent to define the following operation + on partition
which sounds like concatenation on list

I'm using signal.alarm to time out computations that take too long. In
most cases they work, but sometimes they don't. The CPU stops

forever. I know this is due to a lack of sig_on/sig_off
In fact, it really appears as though the place the code is getting
stuck at *is* properly wrapped with _sig_on and _sig_off. What could
be happening?

ignored when it does go off. This is bad when someone else
