Appears in sequences

• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 34.at n=8A031712
• Consider the sequence b(0)=127 and for n>0, b(n) is the least prime of the form k * b(n-1)^2 - 1 where k is a multiple of 6. This sequence gives the values of k.at n=10A110849
• a(n) = 81*n^2 + 9.at n=16A157888
• The number of monic integer polynomials of degree n all of whose roots are distinct and of modulus at most 1.at n=29A280709
