OEIS Sequences

Fixed points of A153212: After a(1) = 1, numbers of the form pi1i1 * pi2i2-i1 * pi3i3-i2 * ... * pikik-ik-1, where pi's are distinct primes present in the prime factorization of n, with i1 < i2 < i3 < ... < ik, and k = A001221(n) and ik = A061395(n). A242421
After a(1) = 1, the sequence is always extended with the smallest divisor d (not yet present in the sequence) of the last term t. If d doesn't exist, we extend the sequence with tt (t concatenated to itself). If tt doesn't produce a new d, we extend the sequence with ttt, etc. See the Comments section for more details. A348871
a(n) = concatenation of n3 with itself. A175605
Palindromes that are the sum of two positive cubes. A162710
Numbers k such that sum of square of prime divisors of k equals sum of prime divisors of k+1. A228181
7n concatenated with itself. A206529
Palindromic numbers such that the sum of the digits equals the number of divisors. A263720
a(n)/144 is the maximum squared volume of a tetrahedron with the sum of its integer edge lengths equal to n. A371073
