Hello, help me in this idea, want to join row and column, i.e. 3 vertical and 4 horizontal and vice versa, i.e. in a 7 x 7 array I join 3 segments and mirrors, if three symmetrical segments of us are number hit = lottery 6/49
Perhaps the array below may be of some use to you. So, 3 numbers in a row, 4 numbers in a column. And since 7 * 4 is more than 7 * 3, 2 and 6 columns sacrifize you, once you least like these two numbers in a row.
x0xx000
x0x0x00
x00x00x
x000x0x
00xxx00
00xx00x
0000xxx
I believe that this mirror array and is together cover all 10 combinations of different numbers of 2 and 6:0 pm its first six lines. That is, 12 lines with eight mirror and 4 combinations containing two lines repeated only (symmetrical) combinations. The last line contains the number 6 (mirror 2). Hope this helps with your problem.
To cover all 35, I don't know if you can compose five such arrays. It would be a lot of work to try to (if you don't know any formula to help you, what not to do). But certainly can't be with arrays of mirror, since there are five of them, then at least one of them must mirror themselves. But there are ony 3 combinatios only, not seven.
Best wishes

    1st 2nd 3rd 4th 5th 6th 7th = positions
    1st 0 0 0 x x x x
    2nd x
    3rd x
    4th x
    5th 0
    6th 0
    7th 0 = positions
    Goal is a 6/49 lottery pick up small awards that fall within the segments when, if it crosses the line with column

      Hello, if the first horizontal line with xxx segment, crosses with the other 7 vertical lines 0000, we have 49, 49 x 7 = 343 then has to make 0000 per vertical line = 49x7
      343 = total 686 lines make the mirror, Union

        Hello, of course when it mounts the 7 x 7 array cannot be in ascending order
        Must be random
        Example =
        .15 .23, 48, 02 12 31 42 29
        10. ...
        18
        49
        28
        45
        06
        17
        The Assembly of the rows and columns of numbers tends to be random, couple take more numbers
        When crosses, row and column, in a raffle at a number 3 and is 3 in a column, has has good prizes
