The extended Grassmann algebra theory and routines were developed by John Browne.

The calculus routines were written by David Park who also designed the user interface for GrassmannCalculus.

You can contact David Park at: djmparkjr [at] gmail [dot] com.

David is working with John Browne's Estate in popularizing John's work and is a good initial contact should you like to help.
