Now that I have given you my way in grouping numbers, I can only add at present that in the case of the UK Lotto there would actually be 8 groups of numbers and not 4 and the reason for that is because there is 7 numbers coming out and they would be in the group of 8,something like the example below.
g1 g2 g3 g4 g5 g6 g7 g8
1 3 5 7 9 11 13 15
a1 a2 a3 a4 a5 a6 a7
Number 1 is group 1 through to Number 15 which is group 15, and 1 to 15 represents the 49 numbers in the UK Lotto, "if you can't follow any thing in what I am doing then you can ask, or if you have any other questions", only I can not give possitive info over an open site, so I will be giving clues and leave the rest to your imagination.
Now a1 to a7 represents the winning numbers and they fit through the space a1 being 2 and and a7 being 14, that is the simple way I have in explaining to you what actually happens. The reason I do it this way is simple when you search for a number you get a number and a lot of other numbers but when you search for the open space that "YOU" have to form for the number, you get that space, try it and you will get the answer the answer does not come from one line you will need a lot more. I am going to finnish at present as this PC is giving me some problems today.
