 OFFSET 2,1 COMMENTS This is to the tribonacci sequence what A030427 is to the Fibonacci sequence. LINKS 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 Adjacent sequences:  A113839 A113840 A113841 * A113843 A113844 A113845 KEYWORD easy,nonn AUTHOR Jonathan Vos Post, Jan 23 2006 STATUS approved
