COMMENTS

This is to the tribonacci sequence what A030427 is to the Fibonacci sequence.

LINKS

Table of n, a(n) for n=2..33.

FORMULA

a(n) = A000040(A000073(n)).

EXAMPLE

a(2) = prime(tribonacci(2)) = prime(1) = 2.

a(3) = prime(tribonacci(3)) = prime(1) = 2.

a(4) = prime(tribonacci(4)) = prime(2) = 3.

a(5) = prime(tribonacci(5)) = prime(4) = 7.

a(6) = prime(tribonacci(6)) = prime(7) = 17.

CROSSREFS

Cf. A000040, A000073, A030427.

Sequence in context: A032236 A128776 A117387 * A032161 A265801 A098738
