OEIS Sequences

a(n) = (12·n+1)*(12·n+11). A1538

For any number n > 0, let f(n) be the function that associates k to the prime(k)-adic valuation of n (where prime(k) denotes the k-th prime); f establishes a bijection between the positive numbers and the arithmetic functions with nonnegative integer values and a finite number of nonzero values; let g be the inverse of f; a(n) = g(f(n) * f(n)) (where i·j denotes the Dirichlet convolution of i and j).
