Alois P. Heinz, Table of n, a(n) for n = 0..8
EXAMPLE
For n = 3, a(3) = Fibonacci(Catalan(3)) = Fibonacci(5) = 5.
MAPLE
a:= n-> (<<0|1>, <1|1>>^(binomial(2*n, n)/(n+1)))[1, 2]:
seq(a(n), n=0..8); # Alois P. Heinz, Jan 20 2017
MATHEMATICA
Fibonacci[CatalanNumber[Range[0, 7]]]
PROG
(PARI) for(n=0, 7, cn=binomial(2*n, n)/(n+1); print1(fibonacci(cn) ", "))
