The idea is that we calc each next number manually; we know that next number is one of 3 possible routes: to increase 1st expo, 2nd or 3rd by 1. So we calc all 3 numbers (what they will become with increased expo and pick minimal), we increase expos of taken step, save number and repeat all again.

ah funny I forgot to put something in there. Usually I write there a feeling or greeting "hello" or 'nice' or something... As long as it's not empty, it serves as True
