No problem that you're hijacking the thread -- I'm glad ginv is getting
discussed.I'm removing the mention of it from my talk, thou
Arghh, I'm very suspicious of this ginv. (Sorry to be hijacking the

They timed Magma on a 32 bit 1 GHz Pentium III and ginv on a 64 bit
AMD Turion 3400.

OK, I see the gcd functions and factorisation, thanks. I was of course
looking in the polynomial module in the documentation and source code,
not the coefficient module.
GCD seems somewhat developed, with the Zippel algorithm for sparse
GCD, Brown's modular GCD and the Heuristic GCD. There's no h

Actuallly he was very modest and used the term "not slower" than
maple.

Hi William,
At the start of your talk in the pdf, the irc chat seems to have the
lines cut off.
Also at the end of the pdf you mention that SAGE will use the new
russian library ginv for poly gcd and factorisation. I didn't seem to
be able to find functions in the user's guide in the tarball for
