OEIS Sequences

Triangle read by rows: a(n,k) is the number of k X n matrices which are the first k rows of an alternating sign matrix of size n. A297622

Fixed points of A153212: After a(1) = 1, numbers of the form p_i1ⁱ¹ * p_i2^i2-i1 * p_i3^i3-i2 * ... * p_ik^ik-i_k-1, where p_i'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

Ordered m for which m = k³*a·b*(a⁴ - b⁴) determine (unique) solution triples(k,a,b), where k=1,2,3,... and (a,b) are coprime pairs, not both odd (i.e., of opposite parity). A81779
