Indeed there is. Many thanks for spotting this error. It has been fixed in
fix#10 that has been just released on Friday.

which makes it even more embarrassing... This is fixed as well.

Why is GAP not able to compute associates in the ring of Gaussian
Integers ? :

gap> Associates(Integers,2);
[ -2, 2 ] # Correct
gap> Associates(GaussianIntegers,2);
Error, <D> must be a domain or a set in

This is a stupid quirk in the list of stored `Units' for the
`GaussianIntegers' which did not form a set. This has been fixed in fix#10
as well.

Many thanks and best regards,
