Robert H. Lewis  
Fermat is a computer algebra system that does graphing, and symbolic and numerical calculations. Fast and economical of space, the main version is oriented toward polynomial and matrix algebra over the rationals and finite fields; Smith normal form; polynomial and rational function arithmetic; determinant, normal forms, and inverse of matrices with multivariate polynomial entries over Z, Q, Zp, finite fields, or more complex fields; sparse matrices; characteristic polynomials; and gcd of multivariate polynomials over Z, Zp, or finite fields. There is also a "float" version for graphics. Take the Fermat Tests to compare it to other computer algebra systems, or read a preprint of a paper that compares different systems (in PostScript form). Manual, FAQ, update history, and downloading instructions also available.
