Coxeter is a computer program for the study of combinatorial aspects of Coxeter group theory, particularly those related to the Bruhat ordering and Kazhdan-Lusztig polynomials.

The main capabilities of the program are the following :

Reduced expression and normal form computations;
Bruhat ordering;
Ordinary Kazhdan-Lusztig polynomials;
Kazhdan-Lusztig polynomials with unequal parameters;
Inverse Kazhdan-Lusztig polynomials;
Cells and W-graphs.

Note: this port is specially crafted to be used with SageMath, with patches from Sage.
