COMMENTS

Apart from a(2), a(n) is in {0, 1, 2}. Almost all terms are 0 by the Prime Number Theorem. - Charles R Greathouse IV, May 26 2011

Table of n, a(n) for n=1..105.

EXAMPLE

a(1)=0 because A176100(1)=0 < 1(nonprime) < A176100(2)=2; a(2)=3 because A175100(2)=2 < 3(odd prime) < 5(odd prime) < 7(odd prime) < 8=A176100(3).
