from Nick Koutras' LottoDesigner ws
Here's an example of a wheel:
LD(49,6,3,6)=55
LD = Lotto Design
49 = V (Maximum Lotto Balls)
6 = K (Drawn Balls)
3 = T (Minimum Guarantee/Hits)
6 = M (Maximum possible Drawn)
55 = B (Tickets of the Design)
This wheel will guarantee at least a 3-hit with 55 lines played.
