Each tableau of length 30 is encoded by two decimal digits, where an on bit in each digit means that the associated number is composite:

 First digit: 30n+1   30n+7   30n+11  30n+13

Second digit: 30n+17  30n+19  30n+23  30n+29

The colored digits above are characters where one of the bits is pre-determined due to a multiple of 7
