See A135817 for references and links for the Wythoff representation for n>=1.

Table of n, a(n) for n=1..105.

a(n)= number of applications of Wythoff's A sequence A000201 needed in the unique Wythoff representation of n>=1.

6 = A(A(A(B(1)))) = AAAB = `1110`, hence a(6)=3.

Cf. A135817 (lengths of Wythoff representation), A007895 (number of 0's (or B's) in the Wythoff representation).

Sequence in context: A047983 A070812 A061865 * A078804 A071465 A197117

Adjacent sequences: A135815 A135816 A135817 * A135819 A135820 A135821
