Yes, I like that - I need to learn about "lift" and "parent".

I thought I'd try to install Sage on an external disk, but I ran into
two problems: the hard disk file system doesn't support symbolic
links, and my laptop's distribution (Suse 9.3) is too old to compile
Sage. So until I get around to upgrading my laptop or its software
(which I'm loathe to do,
Many thanks for an incredibly fast response. I am very impressed!
Sorry about my confusing reference to incorrect old md5sums. They are
all indeed correct. I perhaps should have just said they appeared to
be in the wrong place.

This is the md5sum straight from the server:

Where might i find md5sum hashes for the sage-vmware-3.2.1.zip for MS
Windows. The details of incorrect old builds still appear to be
resident in the folder!

You can also do the following:
M = random_matrix(IntegerModRing(10), 3, 3)
Madj = M.parent() (M.lift().adjoint())
In other words, we lift M to a matrix over ZZ, compute its adjoint and
reduce it mod 10 again (by "coercing it into the parent of M" in sage-
speak).
