Distance between consecutive elements of the multiplicative group of integers modulo n [PDF]

Notes on Number Theory and Discrete Mathematics
For a prime number p, we consider its primorial P:=p# and U(P):=(ℤ/Pℤ)^× the set of elements of the multiplicative group of integers modulo P which we represent as points anticlockwise on a circle of perimeter P.
