Ahem. Speaking as a defrocked mathematician, group arithmetic is _not_
modular arithmetic. It's a strict superset (and includes "ordinary"
arithmetic).

Actually, strictly speaking, putting "arithmetic" and "group" together
doesn't make much sense, since groups only have a single operation.

Cheers,
