OFFSET

LINKS

Table of n, a(n) for n=0..65.

FORMULA

Concatenation of F(n - 2) copies of F(n), for n >= 1, where F = A000045 (Fibonacci numbers).

EXAMPLE

In A003849, the initial segment (s(0),...,s(6)) = (0,1,0,0,1,0,1) first repeats at (s(8),...,s(14)), so that a(6) = 8.

MATHEMATICA

s = Flatten[Nest[{#, #[[1]]} &, {0, 1}, 12]]; b[m_, n_] := b[m, n] = Take[s, {m, n}]; q = -1 + Flatten[Table[Select[n + Range[2, 1600], b[#, n + # - 1] == b[1, n] &, 1], {n, 1, 120}]]

CROSSREFS
