OEIS Sequences

a(0)=1; a(n) = 10ⁿ + 1, n >= 1. A533

Representation of n in base of Fibonacci numbers (the Zeckendorf representation of n). Also, binary words starting with 1 not containing 11, with the word 0 added. A14417

Numbers whose square is a palindrome. A2778

Sums of two powers of 10. A52216

a(n) = 10ⁿ + 1. A62397

Palindromes only using 0 and 1 (i.e., base-2 palindromes). A57148

If n = 2^a * 3^b * 5^c * 7^d * ... then a(n) = a + 10·b + 100·c + 1000·d + ... . A54841

Sums of 2 distinct powers of 10. A38444

The part of n in base φ left of the decimal point, using a greedy algorithm representation (more precisely, using the Bergman-canonical representation). A105424

Minimal (or "greedy") Lucas representation of n, in which L(0) = 2 and L(2) = 3 are not allowed in the same representation (hence the correct representation of the integer 5 is 1010 rather than 101). A binary system of integers with Lucas numbers (A000032) as a base. A130310
