Reduced residue system[edit]
A reduced residue system modulo n is a set of (n) integers such that each integer is relatively prime to n and no two are congruent modulo n. Here denotes Euler's totient function.
Facts[edit]
- If {r1, r2, ... , r(n)} is a reduced residue system with n > 2, then (mod n).
