| Check in the order all odd gentle numbers between first_n and last_n, and if print_bad then print all bad numbers between first_n and last_n (included). The consequence of the result is that: if (all numbers < first_n respect the conjecture) and (all perfect squares < last_n respect the conjecture) and (all bad numbers < last_n respect the conjecture) then all numbers < last_n respect the conjecture.
