Hi Jason,
I looked at your work at #3048. Are you aware of the "formulas" that
can be used to compute individual entries of L and U, in something of
a recursive fashion (lower right entries of each matrix depend on
already computed upper left entries of both L and U)? Looks like it
would only r

Ok, note that this is rc1 on Fedora 10, 32 bit:
The followin tests failed:
sage -t "devel/sage/sage/s
It seems confusing and inconsisent that for a matrix m, m.change_ring(R)
returns m when R==self.base_ring(), but otherwise returns a copy of m
(coerced to the right ring).
If you always just do new_mat = m.change_ring(R), you don't know if
you're working with a copy of m or a new version of m,

If I were to attempt to add LU decomposition to general matrices in
Sage, where would I start? I could write a naive algorithm, but I also
found an implementation in linbox. I suppose there might be an
implementation in other libraries we include.

I was checking port 8000 - the 8 is a typo.

Hi there,
running some programs that deal with subsets of groups I realized the
following behaviour
sage: G = AlternatingGroup(4);
sage: g = G((1,2,3));
sage: cl = Set([x*g*x^(-1) for x in G])
sage: A = Set(G.centralizer(g));
sage: A, cl, A.intersection(cl)

FWIW,
sage-4.0.1.alpha0 compiled without any hickups on my Blade 2000 running
Solaris 10 update 6.
Again, like any version of Sage I've tried (including the binary Micheal
compiled), the GUI interface, with
'notebook()'
will not work for me. I'm unable to find any server listening on port
