I'd like to use the Damm algorithm to generate check digits for codes with a 32-character alphabet. The algorithm itself is easily applied to any base (except 2 or 6). The difficulty is the necessary look-up table, which must be a totally anti-symmetric quasigroup with a single character (usually 0) down the main diagonal.
The Wikipedia page gives a table for base 10, and the Python implementation gives a table for base-16, but I haven't found a base-32 example. Does anyone have a suitable table for base-32?
