22:14 CoCoA-5 Bug #1746 (Feedback): ManExamples target: need to reset VerbosityLevel
- I tried running @make ManExamples@ and was surprised to see verbosity output (for @IsLRSDegenerate@).
I think each e...

18:59 CoCoA-5 Bug #1745: Printing of Hilbert series via indent
- I think we can leaving printing in a list as it is (for the time being).
Tagged values are (often) ones which we pri... -

22:07 CoCoA-5 Slug #1629: RingElem slow with many indets
- Should we advance this issue to "feedback"?

22:05 CoCoALib Design #1744: Implement GBMill (aka Groebner Framework)

15:42 CoCoALib Feature #1743 (In Progress): Implement Truncated GBases for homogeneous input
- Truncated GBases can be quite useful.
Find a way to implement them without duplicating to much code.
Ideally we sho...

09:26 CoCoA-5 Slug #1629: RingElem slow with many indets
- I have just checked out Anna's update, and confirm that the first example in comment 8 is now fast. Thanks to Anna.

09:24 CoCoALib Slug #967: Improve saturate
- My suggestion above is not quite right.
The poly which I am saturating with respect to must be reduced modulo @I@.

20:36 CoCoA-5 Slug #1629: RingElem slow with many indets

20:32 CoCoALib Slug #967: Improve saturate
- Let @P@ be a poly ring with indets @x[1]..x[n]@ and @y[1]..y[m]@.
Suppose the gens of ideal @I@ involve only @x@ ind...
