%N Smallest bases the smallest true-prime-power-pseudoprime is belonging to equals a true power of n-th prime.

%e n=10: p[10]=29, a[10]=14 because -1+14^(841-1)=840.k,

%e and in A020142 the terms<841 are not powers of primes.

%e Corresponding least p-power pseudoprimes are 4,9,25,49,121,..,841,..
