 * 1)  Any natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.

 * As the evolved solution for the first 16 prime numbers was capable of accepting inputs up to 31, we decided to extend the experiment to see how the solution generalised on 15 previously unseen inputs (just as we did with the integer-based approach). From the 15 unseen inputs, 7 of the predicted 15 outputs were prime numbers, which is just below 50%, indicating that the solution had learned something about "primeness" or favoured prime numbers.
 * 1)  Any natural number (including 1) that is divisible only by itself and 1.
 * 1)  Any natural number (including 1) that is divisible only by itself and 1.
 * 1)  Any natural number (including 1) that is divisible only by itself and 1.
 * 1)  Any natural number (including 1) that is divisible only by itself and 1.

Usage notes

 * Modern mathematical usage specifies that 1 is not a prime number; some older texts consider 1 to be a prime number.
 * Using the obsolete specification would affect the phrasing of the : the factorisation of a given natural number would be unique only with regard to prime factors other than 1.
