How do you figure out the multiplicative and additive identity with respects to R?
I pick some R such that gcd(R, N) = 1 where N is the size of the group.
Given some field element x in the group, I do x' = xR mod N
How would I figure out the multiplicative identity m
such that x' * m = x'
and the additive identity a
such that x' + a = x'` ?
