Hi Bill,
Of course, I'd like to provide MScaLAPACK etc.
Thanks,

Hi Jason
I'm Nakta, Maho, a principal developer of MPACK.
I've never used ALGLIB before...
thanks,

Hi Jason,
That all sounds great, I am available for a summertime push on
permutation groups as it will fit nicely with some other plans I have.
Over on the centralizer thread, I think David Joyner volunteered me as
"leader." I don't think I want to go that far, in particular because

If I'm defining a new class and I want to implement a TestSuite for

Hi Andrey,
Just to clarify, I only wanted to subclass Cones, but not Fans. The
fan is a container class for cones and that doesn't change. In
particular, I never felt the need to add any functionality at that
level in my code.
As for sharing of cached data, I think a clearer way would be to

Since the current Sage implementation of derangements is a wrapper for
a GAP function, and doesn't always work as you'd like, I've bunged the
first draft of a more complete native implementation of derangements
up as ticket #9005.
cheers,
Alasdair
