Generate all the formations a number each letter
* Example we have in the letter A = 4 NUMBERS 01,05,17 21
Letter b == 2,6,18,22
C = 3.7, 19.23
D = 4,8,20,24
And
Up to h =
Formations = 01,18,23,24
We have a number for each group, this is the criterion

use the criterion of formation = only one number in each of the 8 letters, each letter has 4 numbers exeto letter h

I forgot to mention if the 1st number of a group is from the 1st the other 3 numbers can not be from the same position
1st 2nd 3rd 4th*
1 5 17 21 = a
2 6 18 22 = b
3 7 19 23 = c
4 8 20 24 = d
9 13 25 5 = e
10 14 26 30 = f
11 15 27 31 = g
12 16 28 = L
* In group (L) only 3 because it goes up to 31
* So if I choose 05 it's from the 2nd position and I can not repeat the 2nd position
* In the others.
