- Integers x 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).at n=28A067739
- Numbers n such that n^3 can be represented as sum of (at least two) consecutive squares.at n=22A163390
- Integers m such that m^3 is the sum of two or more consecutive integer squares.at n=39A212018
