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

Trajectory of binary number 10110 under the operation 'Reverse and Add!' carried out in base 2. A58042

Sums of 3 distinct powers of 10. A38445

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

Carryless binary square of n; also Moser-de Bruijn sequence written in binary. A63010

Binary representation of the x-axis, from the left edge to the origin, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 505", based on the 5-celled von Neumann neighborhood. A282796

Binary representation of the x-axis, from the origin to the right edge, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 545", based on the 5-celled von Neumann neighborhood. A283010

a(n) = A010062(n) written in binary: a(n+1) = a(n) + hammingweight(a(n)) in binary. A230297
