Table of n, a(n) for n=0..12.

Formula

a(n) = A000040(10^n) modulo A001358(10^n). a(n) = A117322(10^n). a(n) = A006988(n) modulo A114125(n).

Example

prime(10^0) modulo semiprime(10^0) = 2 mod 4 = 2.
prime(10^1) modulo semiprime(10^1) = 29 mod 26 = 3.
prime(10^2) modulo semiprime(10^2) = 541 mod 314 = 227.
