I am using sixteen combinations optimized, to create a matrix of all forty nine numbers played.
The combinations (16):
03 05 11 17 47 49…08 15 21 28 34 39…02 10 11 12 38 49…11 14 15 16 21 43
09 10 12 14 26 41…02 13 17 30 33 45…01 09 13 19 26 45…01 10 25 31 42 49
06 12 18 20 36 49…04 07 10 27 38 42…19 22 35 37 40 48…05 22 29 30 32 46
11 23 24 29 33 44…01 06 16 31 44 47…08 13 31 34 46 48…04 09 11 12 19 31
The final total cost is $16.
