An Ahri N- probable prime with (a,b)=(10,7).

Ahri N- primes are primes of the form (a^p-b^p)/(a-b) with a>b>0, gcd(a,b)=1, p odd prime.

Ahri N+ primes are primes of the form (a^p+b^p)/(a+b) with a>b>0, gcd(a,b)=1, p odd prime.

(11^26393+6^26393)/17 is an Ahri N+ probable prime with (a,b)=(11,6), but it is to small for this PRP top.
