Shown are timings for solving systems of linear equations represented by sparse square integer matrices. The experiment was performed on an Intel Xeon 3.07 GHz 64-bit Linux system, with a time limit of 4200 seconds. The number at the bottom tells how many times faster Mathematica 9 is than Maple 16.

Shown are timings for solving systems of linear equations represented by square integer matrices with a permuted triangular block structure.
