Sequence numbers and descriptions below are taken from OEIS.
A032302: G.f.: Product_{k>=1} (1 + 2*x^k).
A065759: For a number n of length l, let f(n) be the sum of the products of the first i digits of x multiplied by the last l-i digits, for i from 1 to l-1, e.g., f(1234) = 1*234 + 12*34 + 123*4 = 1134. Sequence gives n such that f(n) = n.
A095694: T(n,3) diagonal of triangle in A095693.
A098845: Numbers k such that 4^k - 2^k - 1 is prime.
A138938: Indices k such that A019326(k)=Phi[k](8) is prime, where Phi is a cyclotomic polynomial.
A151801: Number of n X n binary arrays with rows, considered as binary numbers, in strictly increasing order, and columns, considered as binary numbers, in nondecreasing order.
A173303: Row sums of triangle A173302.
A175523: a(n)=a(n-1)+ p, where p is the least prime whose first digit equals the first digit of a(n-1) and p>=a(n-1)
A218628: Number of partitions of n+7 with largest inscribed rectangle having area <= n.
A265737: Consider any concatenation of the type n = concat(a,b). Sequence lists numbers that are the sum of the products of some of such couples a and b.
