Dear Sage team,

this time i have two groups of questions.

1.
My main project is the creation of a data base of cohomology rings of
finite p-groups (coefficients in GF(p), of course). For each group in
the data base, it should provide
- a quotient of a graded-commutative ring, isomorphic to the
cohomology ring; these are data in Singular.
- special subgroups, namely maximal elementary abelian subgroups and
the greatest central elementary abelian subgroup; these are data in
Gap.
- the restriction map for each special subgroup; again, data in
Singular.

Question to group theorists:
What further informations do you wish to be part of such data base?

Question to everybody:
What tools/packages are available for Sage that help to create and
maintain a data base (please with hints to tutorials/manuals)?

2.
There is a long thread about improving linear algebra (specifically
over small fields) in Sage:
http://groups.google.com/group/sage-devel/browse_thread/thread/aa4edc241ca4d6bb/df55b9b03e056e4d?hl=en&lnk=gst&q=M4RM#df55b9b03e056e4d

Has this improvement become part of the Sage distribution? Or is it an
optional package? Personally, I specifically need fast operations
"matrix times vector", "vector times scalar", "sum/difference of
vectors", "echelon form of a matrix".

Yours
         Simon
