Sparse Integer Matrices Collection
Collection of matrices used in exact computations. Most of them are sparse with integral or modular coefficients, some have rational or polynomial entries.

A sparse matrix format is used which consists of a series of triples (the format is called SMS, Sparse/Symbolic Matrix Storage). The first triple is number of rows, number of columns, and a letter ("M" for integer/modular, "R" for rational, etc.). The following triples signify non-zero entries and have the form row-index, col-index, value. They must be in increasing lexicographical order. The last triple is ``0 0 0'' used as an end marker.
For example :

32 3200 M
1 1 345
1 2 -23
2 1 77
2 200 31
30 3101 11
0 0 0
denotes a 32 by 3200 matrix with 5 non-zero entries, three of which are clustered at the top left.
