I got a fun little question from Jean-Marie by email the other day. With the disclaimer that I don’t really have the time to solve that many puzzles and therefore probably wont be able to give you a solution to puzzles like this one. This one triggered my curiosity and I managed to find a rather cure solution.
Therefore I will post it to you all and let you wonder a bit about it. If you find the solution feel free to post it in the comments.
The question is simple:
Find all the primes that contain 9 different digits (0 excluded).
Good luck 🙂
