OEIS Sequences

Integers·such that for some integer y we have uphi(x) = uphi(y) = x-y, where uphi(n) = A047994(n) is the unitary totient function: If n = Product p_i^e_i, uphi(n) = Product (p_i^e_i - 1). A67739

If n = D0·10⁰ + D1·10¹ + D2·10² + .. + Dk·10^k define f(n) = D0·0¹⁰ + D1·1¹⁰ + D2·2¹⁰ + .. + Dk·k¹⁰ (e.g. if n = 421 then f(n) = 4·2¹⁰ + 2·1¹⁰ + 1·0¹⁰ = 4098). Sequence gives values of n such that f(n) is divisible by n. A65110
