Jean-Marie Sainthillier submitted a Comment to Problem 2910. Mersenne Primes vs. All Primes

Hello Grant, I don't know if it's a lot of work but it could be a good idea to add a Prime Numbers group 2 with more difficult problems. I think about beautiful Ned's problems (primes ladders, Longest prime diagonal, Twins in a window ...).

@goc3 To be clear, I speak about Solution 1720010 of Alfonso (https://www.mathworks.com/matlabcentral/cody/problems/44755-lights-out-4-5x5-8-moves/solutions/1720010). Incredible no ?
