Sorry but I have to ask, are you familiar with the nextprime() CAS command?

Yes for sure! But you are right to ask. In fact, I was looking for primes starting by 82 and ending by 1, like 8221 or 82231.
Brute force algorithm is to increase N in 82N1 and test if it is a prime number.
I noticed the above bug, so I tried to isolate the bug using isprime in this superb algorithm
