Can you clarify this a bit?
Obviously, there's a difference between the product of matrices of
permutations and the matrix of the product of permutations. That is, they
are 'reversed.' But, multiplication in the matrices is not the same
operation as the one imposed on the elements from a group.
How does this sound.
1) We add an environment variable SAGE_ATLAS_THREADS
2) If unset, then the behavior is unchanged, so we build an unthreaded
ATLAS. 3) If set to auto:
$ export SAGE_ATLAS_THREADS=auto
then we let ATLAS automatically determine the number of threads. (I think

world domination has a very intimidating (naziesque) connotation for
me (I do not think only for me, but I cannot know). Sage is great, but
that makes me shiver.

Hi all,

This is definitely still present in sage-4.5 (at least, William tried
it on his laptop and said he hit it). The underlying issue is

Hi,
I put my experimental giac spkg here:

then delete the file it complains about (repeat, lather), type make
