Number of primitive roots formula
WebIf we consider a = 3, we will find it's a primitive root modulo 31, so the sequence will have period 30. It turns out that m has a pimitive root if and only if m is equal to 1, 2, 4 or of the form 2 α p β, where p is an odd prime, α = 0 or 1, and β ≥ 1. WebPrimitive roots calculator ...
