It's an arrangement of 25 odd numbers of the lotto 6/49 of a way of giving onto every
horizontal, vertical and oblique diameter the identical sum of 157. To note that the Odd
Magic Circle is more complicated than the Even Magic Circle because of a supplementary
number which is "1". This number which is situated in the center of the circle repeats in
every combination and in more it gives a combination of 7 numbers instead of 6.
