Dear GAP-forum,

In his message of 24th of August, Allan Adler writes:

GAP has attractive features that lend itself to such computations,

namely the facility for working with groups, character tables,

representations, etc. But it is weak in more traditional computer

algebra such as polynomial manipulation.

Invariant computations (which were the initiator for this thread) surely

will need polynomial arithmetic in several variables, which is - at the

moment - not very feasible in GAP, as Joachim Neub"user already pointed

out.

However, if you need polynomial factorisations (over Q or an algebraic extension

Q(alpha)) and basic polynomial routines like resultant etc.; there will

be routines in a future version, that provide these functions. (They are

basically finished and just have to be incorporated.)

Probably this is of some use.
