Table of n, a(n) for n=0..14.

Formula

a(n) = A000045(A001591(n)).

Example

a(0) = Fibonacci(pentanacci(0)) = A000045(A001591(0)) = A000045(0) = 0.
a(1) = Fibonacci(pentanacci(1)) = A000045(A001591(1)) = A000045(0) = 0.
a(2) = Fibonacci(pentanacci(2)) = A000045(A001591(2)) = A000045(0) = 0.
a(3) = Fibonacci(pentanacci(3)) = A000045(A001591(3)) = A000045(0) = 0.
a(4) = Fibonacci(pentanacci(4)) = A000045(A001591(4)) = A000045(1) = 1.
a(5) = Fibonacci(pentanacci(5)) = A000045(A001591(5)) = A000045(1) = 1.
a(6) = Fibonacci(pentanacci(6)) = A000045(A001591(6)) = A000045(2) = 1.
a(7) = A000045(A001591(7)) = A000045(4) = 3.
a(8) = A000045(A001591(8)) = A000045(8) = 21.
a(9) = A000045(A001591(9)) = A000045(16) = 987.
