CBraid is a C++ library originally written by Jae Choon Cha. It allows various computations on braid groups, such as normal forms. The code in this project is based on his final version of 2001/12/07 and distributed under the GPL.

The library has been updated to run on modern compilers, and has been merged with Braiding version v1.0 (2004/10/04) originally written by Juan Gonzalez-Meneses and distributed under the GPL. Maria Cumplido contributed some code for computing sets of sliding circuits.

The code is maintained by Jean-Luc Thiffeault.
