• It would be a very tedious, time-consuming task! Meanwhile, the payoff would be insignificant (the way I see it). My lotto software (including the freeware) uses built-in filters that eliminate some of the patterns you mention. For example, the software does not generate all-even or all-odd lotto combinations. The sum-totals of the lottery combinations fall within a range based on the standard deviation.

Later, I wrote new lotto software programs named UserGroups, components of the comprehensive collections of lotto software named Bright. They work with groups of numbers: odd, even, low, high, frequency, sum totals. The software can generate quickly, in memory, all lotto combinations generated by enabling the filters above. There are no direct formulas; there are only algorithms. The calculations are, however, very fast and absolutely accurate.

: Is there a way to create a formula, to calculate the odds for a combination of the following possibilities; without running all the different possibilities, through each lottery combination? It's easy to figure out the odds for each possibility, per filter; but to figure out the odds, for a combination of the filters, is driving me crazy. To run all the possibilities through each lottery combination, would be very time consuming; and I'd doubt that you could have a text file that big. A formula, if possible, would be the only solution. If you can help, or point me in the right direction; email me at cjames14@qwest.net. I'd REALLY appreciate it!!!

: Filters:

: Excluded #'s: (1-49) 49 possibilities
: Sums: (21-279): 259 possibilities
: Even #'s: (0-6): 7 possibilities
: Low #'s: (0-6): 7 possibilities
: Consecutive #'s: (1-6): 6 possibilities
: Lowest # Drawn: (1-44): 44 possibilities
: Highest # Drawn: (4-49): 44 possibilities

: What makes it hard to calculate the odds; is that changing one filter affects the other filters. It's hard to figure out, how many combinations are left in the remaining filters; and then to filter from the remaining.
