What I would love to understand is how to extend the Lenstra–Pomerance–Wagstaff conjecture to...

Frequency of REPUNIT primes

Frequency of REPUNITS

Generalized repunits are [$]{a^n-1} \over {a-1}[/$]

Thus if a =2 we have the Mersenne Numbers The Mersenne Exponent primes are 2, 3, 5, 7, 13, 17, 19, 31, 61, 89........
