OEIS Sequences

Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted then there are a pair of central terms both equal to 10. A31423
At stage 1, start with a unit equilateral triangle. At each successive stage add 3*(n-1) new triangles around outside with vertex-to-vertex contacts. Sequence gives number of triangles at n-th stage. A269064
a(n) = a(n-1) + a(round(2*(n-1)/3)) + a(round((n-1)/3)) with a(1)=1, a(2)=2. A33500
Lesser of a,b where n2 = a3 + b3; a,b > 0 and gcd(a,b)=1. The greater of a,b is the corresponding term in A099533 and n, which is used to order this sequence, is the corresponding term in A099426. A99532
(2p-1 modulo p2) + (3p-1 modulo p2), where p = prime(n). A240987
a(n) = n! * ∑k=1..n ( ∑d∣k 1/(d * ((k/d)!)d) )/(n-k)!. A354341
