%N Position of the first occurrence of the n-th prime in A225017, or 0 if prime(n) never occurs.
%C It appears that a large fraction of terms are relatively small, say a(n)<2*n, but they can be rather large. For example, prime(156)=911 occurs first at n=14424 in A225017, so a(156) = 14424.

%e A225017 begins {1,1,7,1,13,11,...}, with offset 0, and the 4th prime 7 occurs for the first time at A225017(2)=7, so a(4)=2. 11 occurs for the first time at n=5, so a(5)=5.
%Y Cf. A225017.
