Timings for computing the null space for integer matrices. Each matrix was obtained by multiplying an matrix with randomly generated entries between and and an matrix with randomly generated 0-1 entries. Experiment performed on an Intel quad-core i7 940 2.93 GHz 64-bit Windows Vista system with hyperthreading enabled, and for computations to finish in 2000s. The number at the bottom tells how many times faster Mathematica 8 is compared to Maple 14.
