| 2025-03-10 |  | | I am interested in the behavior of prime numbers 11, 13, and 37 and also like them. Prime 11 and 13 are the most overlooked primes in terms of them appearing in bigger prime numbers as a set. Prime 37 has some magic in it, and people choose it without realizing why. Strange, really. Checking if a number is prime is easy with this app. Thank you. |
