Dear forum,

I would like to create the ring from Integers mod m, adding primitive root
of unity of degree n.

gap> I:=ZmodnZ(24);
(Integers mod 24)

gap> z:=E(12);
-E(12)^7

gap> ClosureRing(I,z);
Error, no method found! For debugging hints type ?Recovery from
NoMethodFound
Error, no 1st choice method found for `ClosureRing' on 2 arguments called
from
<function>( <arguments> ) called from read-eval-loop
Entering break read-eval-print loop ...
you can 'quit;' to quit to outer loop, or
you can 'return;' to continue

I could understand this, since z and I have different element families.
But whether I need to add some functionality myself, or there is already
available one to construct such ring ?

Sincerely yours,
Alexander Konovalov
