• Number of integers with a shortest addition chain of length n.at n=20A003065
• Numbers n such that n^2048 + 1 is prime (a generalized Fermat prime).at n=25A088361
• Numbers n such that S(n) = 0, where S(n) = (S(n-1) + A000040(n+1))*(-1)^n; S(0)=0, n >= 1.at n=13A131693
• Numbers in A075728 which are not one less than some prime.at n=32A179232
• Let m_n denote the number which is obtained from n-base representation of m if its digits are written in nondecreasing order; then a(n) is the smallest period of the sequence which is defined by the recurrence b(0)=0, b(1)=1, b(k)=(b(k-1) + b(k-2))_n, for k>=2, or a(n)=0, if there is no such period.at n=42A237671
• Numbers k such that Bernoulli number B_{k} has denominator 61410.at n=26A295591
