OEIS Sequences

3-full (or cube-full, or cubefull) numbers: if a prime p divides n then so does p³. A36966

Numbers of the form 2ⁱ*5^j with i, j >= 0. A3592

Achilles numbers - powerful but imperfect: if n = Product(p_i^e_i) then all e_i > 1 (i.e., powerful), but the highest common factor of the e_i is 1, i.e., not a perfect power. A52486

Monotonic ordering of set S generated by these rules: if·and y are in S then x² + y² is in S, and 1 is in S. A192476

a(n) = σ(n) * A003961(n), where A003961 shifts the prime factorization of n one step towards larger primes, and σ is the sum of the divisors of n. A341529

Numbers k such that the decimal expansion of k² contains k as a substring. A18834
