With 60 selections there are total permutations of 8,032,098,711,274,139,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
perming 2 from 60 = 1770 permutations perming 3 from 60 = 34220 permutations just google permutation calculators, not sure about the viability of the system any longer, you could always back test it if you can get the odds available. |

Cheers Ritzy, had just checked that out and doesn't sound like it's a goer.

I use the following method. For example 20 selections and you want to calculate trebles (20 x 19 x 18) divided by (1 x 2 x 3). This would appear to work using RitzyD answer above, doubles 60 x 59 divided by 1 x 2 = 3540/2 = 1770.
