Dear Max, Thank you very much. Now I have no more questions. Just an explanation why I was asking them, actually *after* having read, in the "Reference" GAP manual, that
> TriangulizeMat( <mat> ) > > applies the Gaussian Algorithm to the mutable matrix <mat> and changes > <mat> such that it is in upper triangular normal form (sometimes called > ``Hermite normal form''). The point was that if you search in the net, for instance, what "Hermite normal form" would mean, you may run upon something like this: http://mathworld.wolfram.com/HermiteNormalForm.html . And not much easier with "upper triangular normal form". Also, linear algebra is my favorite subject for some 40 years, partly because it is not dogmatic :D But again, now everything is fixed with my question, and thank you once again.
