The matrix is done and now I have all forty numbers played.

The combinations (16):

06 12 18 20 36 49…08 14 15 21 34 39…02 13 24 31 37 41…12 19 23 29 35 44
14 19 25 33 45 46…02 15 22 30 38 48…11 19 28 34 42 49…02 06 13 28 41 46
03 05 11 17 47 49…04 07 10 27 38 42…09 15 18 19 31 39…05 21 22 29 36 47
05 22 28 33 43 47…01 09 13 19 26 45…05 11 15 22 27 29…01 02 05 18 29 33

The final total price is $24 (already played) + $16 = $40

Good luck to all of you and me. Babar
