A number of different groups have produced implementations of Geometric Algebra in symbolic algebra packages. These include:
 A Mathematica notebook created by Terje Vold.

Clifford Algebra with Mathematica, by AragonCamarasa, et al. arXiv:0810.2412
 A GA module for SymPy. SymPy is a free symbolic algebra package built on Python. The module is maintained by Alan Bromborsky.
 The GA Sandbox and other tools maintained by Leo Dorst’s group.
Maple
For our research we favoured the symbolic algebra package Maple. The initial decision based on a comparison with available tools around 1992.
The software we now rely on was originally written in the period 19951998 using Maple V by Mark Ashdown. The software can be downloaded from
Unless you are running a very old version of Maple you will want version 1.2.2. This supports versions from 9 onwards, and is currently running smoothly on Maple 2015.
