11:18 Design #455: Which sets of generators in an ideal?
- I think we should have @myMinGens@ in every ideal: a "minimal set of generators" is quite a general concept.
We shou... -
10:46 Feature #366: function (CoCoALib) for minimal generators (like old Minimalize)
- What should *minimalize(I)* do?
The cocoa-4 function would create a new ideal (submodule) generated by *MinGens(I)*....

Added new tests. Modified documen... -
15:32 Feature #457 (In Progress): Zero to the power zero, 0^0
