 OFFSET 1,1 LINKS Table of n, a(n) for n=1..62. FORMULA a(n) = A000040(A002808(n)) - A000040(n) = A088982(n) - A000040(n). EXAMPLE For n=3, prime(composite(3)) = 19, and prime(3) = 5, therefore a(3) = 19 - 5 = 14. MATHEMATICA Table[Prime[Composite(n)] - Prime[n], {n, 1, 100}] CROSSREFS Cf. A088982.
