-Generating datasets containing divisibility by first 100 primes as input,
+Generated dataset with uniform random number between 1 and 10^13, containing divisibility by the first 100 primes.
 
-Natural dataset - uniform between 1 and 10^13.
+Non-cheat dataset: uniform, but all numbers have at least one prime factor outside the first 100 primes.
 
-Columns: number | n mod 2 | prime 2 | n mod 3 | prime 3 | ... | prime 541 | mobius
+Columns: number | n mod 2 | prime 2 | n mod 3 | prime 3 | ... | prime 541 | mobius | remainder after 100 primes
