Been working on it for 7 hours now.
Still more to do time wise. Need to finish creating the grid to contain all 715 box combos.
Then I will need to go back and check all 715 combos again to make sure they are all there.
Grid is not going to be as big as I expected.
looks like 13 columns wide and 12 lines tall.
Looks like it will be congested in tight .
Probably tomorrow eve when ready.
