OEIS Sequences

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

Sums of two powers of 10. A52216

Sums of 2 distinct powers of 10. A38444

Multiples of 2 whose digit sum is 2. A69537

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

NegaFibonacci representation code for n. A215022
