• String formed from first n ternary digits found in decimal expansion of Pi.at n=5A065834
• List of Lyndon words on {1,2} sorted first by length and then lexicographically.at n=20A102659
• Sorted list of strings that can be obtained by starting with 12 and repeatedly doubling any substring in place.at n=22A130838
• Number of walks within N^3 (the first octant of Z^3) starting at (0,0,0) and consisting of n steps taken from {(-1, -1, 0), (-1, 0, 1), (-1, 1, -1), (1, -1, 0), (1, 0, 0)}.at n=13A148034
• Smallest number whose sum of cubes of digits is n.at n=34A165370
• 6-digit numbers k such that: (a) the digits of k are from the set {1, 2, 3, 4, 5}, and (b) any digit that appears in k appears at least twice.at n=23A171725
• Numbers for which the sum of reciprocals of square of digits is an integer.at n=12A182452
• Smallest (i.e., rightmost) Lyndon word in the Lyndon factorization of the binary representation of n (written using 1's and 2's rather than 0's and 1's, since numbers > 0 in the OEIS cannot begin with 0).at n=79A211096
• Largest (i.e., leftmost) Lyndon word in Lyndon factorization of binary vectors of lengths 1, 2, 3, ... (written using 1's and 2's rather than 0's and 1's, since numbers > 0 in the OEIS cannot begin with 0).at n=77A211099
• Minimal representation (considered minimal in any canonical base b >= 3) of n in a binary system using two distinct digits "1" and "2", not allowing zeros, where a digit d in position p (p = 1,2,3,...,n) represents the value d^p.at n=31A235860
• List of words of length n over an alphabet of size 9 that are in standard order and which have the property that every letter that appears in the word is repeated.at n=28A273978
