Table of n, a(n) for n=1..55.

EXAMPLE

Pi = 3.14159265358979323846264338327950288... (see A000796).

First occurrence of prime(23) = 83 starts at the 26th digit after the decimal point, hence a(23) = 26.

PROG

(MAGMA) k:=3500; R := RealField(k); [ Position(IntegerToString(Round(10^k*(-3 + Pi(R)))), IntegerToString(NthPrime(n))) : n in [1..55] ]; /* Klaus Brockhaus, Feb 15 2007 */
