The following was confusing me so I'd be grateful if anyone could help out:
In E-World, the only numbers that exist are even integers. An e-prime is an even number that is not divisible by any even numbers. For instance, 6 is an e-prime because it can't be divided by 4 and it can't be divided by 2 in the E-World because 6/2 is 3, which does not exist in this world (and also in E-World, a number is not divisible by itself).
The number 12 only has one factorization as a product of E-primes: 12 = 2*6. (We consider 2*6 and 6*2 to be the same factorization.). Describe all even numbers that only have one factorization as a product of E-primes.
