• a(n) = n^2*(n^2 + 15)/4.at n=19A159833
• a(n) = 94*n^2.at n=19A174337
• For any number n > 0, let f(n) be the polynomial of a single indeterminate x where the coefficient of x^e is the prime(1+e)-adic valuation of n (where prime(k) denotes the k-th prime); f establishes a bijection between the positive numbers and the polynomials of a single indeterminate x with nonnegative integer coefficients; let g be the inverse of f; a(n) = g(f(n)^2).at n=37A297473
• Numbers k such that sigma(k) = psi(k) + tau(k)^2.at n=31A390296
