16:12 CoCoALib Feature #1306: exgcd over integers (ZZ): The cofactors are defined only modulo the lattice of "syzygies" (kernel of the row matrix); the hope is that the vect... John Abbott
16:08 CoCoALib Feature #1306 (In Progress): exgcd over integers (ZZ): Implement a general extended gcd over the integers.
The idea is that the cofactors should be reasonably small.
Pr... John Abbott

Do we want to offer such a command?
Perhaps @OpenOFil... John Abbott
