C = Covering Design, Wheel

v = total numbers (ie. 49)

k = numbers per ticket (ie. 6)

t = minimum hit size (ie. 2)

m = if within the v-(total numbers) have maximum hits (ie. 6)

l = guarantees how many times t-minimum hits will occur within the
design (ie. 1)

b = number of tickets (>= 1)

Example 1: C(31,6,2,2,1,31)

= A wheel(with 31 nbr,6 nbr per ticket, minimum hits 2, if within total numbers have
2 hits, quantity of 2 hits =1, with 31 tickets )

Example 2: C(49,6,3,6,1,168)

= A wheel(with 49 nbr,6 nbr per ticket, minimum hits 3, if within total numbers have 6
hits, quantity of 3 hits =1, with 168 tickets )
