Closing this. -

I'm not confident it always works for ideals in small characteristic.
I hope the... -

- I suggest closing this now.
A refined solution is much more difficult and probably not that necessary.

There are more specific issues now, so I close this. -

- Now using 10.11.
There are still some warning (lots), but compilation has been working fine for ages now.
Closing. -

I realized that the CoCoALib function @myMinimalize@ is just a... -

It should also be dome properly for modules, doing in CoCoALib @SubmoduleOfGBasis@ and @SubmoduleOfMinGens@.
