 A157032 Let d(i) be the i-th digit of the decimal expansion of phi=1.6180339887498948482045868...,so that d(0) = 1, d(1) = 6, d(2) = 1, etc. Then a(0) = 1, thereafter a(n) = d(d(n)). 0

 OFFSET 0,2 COMMENTS This defines a constant 1.368188888908880808110383880... related to Phi in a peculiar way! All digits are one of the first 10 digits of Phi = A001622, so 2, 4, 5 and 7 never appear. [From R. J. Mathar, Mar 14 2009] LINKS Table of n, a(n) for n=0..104. CROSSREFS Cf.
