Elementary functions for association schemes on GAP

Akihide Hanaki


You can get GAP at http://www.gap-system.org/. We suppose the version of GAP is 4.x. Some functions need the package grape 4.4.

Read my file association_scheme.gap on GAP, Read("association_scheme.gap"). Then you can use the following functions.

We use notations and terminologies in [2] and [12]. Let R be a relation matrix.

We use the notation $ (X,S)$ for the association scheme with relation matrix R.
