• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 39.at n=3A031717
• Indices of primes in sequence defined by A(0) = 89, A(n) = 10*A(n-1) - 81 for n > 0.at n=23A101057
• Write n in base 10 as d1d2d3.....dk; for a list of primes P = (p1,p2,p3,....pk) with p1<p2<p3<.....<pk, let A(P,n)=(p1^d1)*(p2^d2)*(p3^d3)*.....(pk^dk) and B(P,n)= concatenation of primes and powers = p1&d1&p2&d2&p3&d3&.......&pk&dk. Then a(n) is the smallest number A(P,n) such that A(P,n)>B(p,n) if it exists, otherwise 0.at n=12A134328
