Table of n, a(n) for n=0..26.

Formula

a(n) = A000045(n)*10^(A055642(A000045(n+1))) + A000045(n+1). - José de Jesús Camacho Medina, Dec 16 2016

Mathematica

AA = Table[Fibonacci[n]*10^(Floor[Log[10, 10Fibonacci[n + 1]]]) + Fibonacci[n + 1], {n, 1, 12}] (* José de Jesús Camacho Medina, Dec 16 2016 *)

Prog

(PARI) glue(a, b)=a*10^logint(10*b, 10)+b
a(n)=glue(fibonacci(n), fibonacci(n+1)) \\ Charles R Greathouse IV, Dec 16 2016
