This is the general purpose way to compute nullspaces in Maple

memory used=11.36GiB, alloc change=333.86MiB, cpu time=95.60s, real time=85.11s, gc time=20.07s

This command gives a significant speedup, but requires advance knowledge that the matrix M is dense and rational.

If the correctness check is skipped, it is much faster
