Primitive root modulo n adding up elements of this multiplicative group? As it happens, sums (or differences) of two primitive roots add up to all elements of the index 2 subgroup of Z/"n" Z for even "n", and to the whole group Z/"n" Z when "n" is odd: No simple general formula to compute primitive roots modulo "n" is known. There are however methods to locate a primitive root that are faster than simply trying out all candidates. If the multiplicative order of a number "m" modulo "n" is equal to formula_2 (the order of Z), then it is a primitive root. In fact
