%N Integers written in base phi, with the "decimal point" omitted.

%C The map 100 -> 011 is used to eliminate every 100 from the minimal representation (A130600).

%C Other sequences are possible for representing integers in base-phi with no occurrence of "00" in any terms - see links.

%e Examples: a(2)=111 because phi^0+phi^-1+phi^-2 = 2, a(3) = 1101 because phi^1+phi^0+phi^-2 = 3, a(4) = 10101 because phi^2+phi^0+phi^-2 = 4.
