关于无阶整数的一点注记

For a fixed natural number m,an integer t is said to possess weak order(modm),if there exists a natural number n satisfyingt~(?) 1≡t(mod m),and t is said to be order-free(mod m) otherwise.We write g(m)for the number of incongruent elements possessing weak order(mod m) and f(m)for the number of incongruent order free elements(mod m).
