👉 The term "stopen" is a mathematical concept related to the set of all positive integers that are not divisible by any prime number greater than 3. It is often used in cryptography and number theory for its properties like primality testing, which can be used to determine if a number is prime or composite. In other words, a stopen contains numbers that are relatively prime to every prime number less than the number itself (i.e., they have no common divisors with these primes). For
