From Gordon Gonsalves:
Combinations! is a combinations generator, ideal for lotto players, but suitable for anyone who needs a program which can generate combinations of a given set of numbers, letters or a mixture of numbers and letters (called "items"). Enter up to 56 different items and have Combinations! produce all 2,3,4... to 10-item combinations of the items you entered in a flash. Alternatively, you can have Combinations! generate a complete set of 2,3,4... to 10-number combinations from up to 99 numbers (eg. all 7-number combinations from 49 numbers). Combinations! can then create a sub-set of the generated combinations at the click of a button (helps lotto players create a manageable set of numbers to play). Generated combinations and sub-sets can be printed or exported to a tab-delimited text file.
What's new in this version:
Can now generate combinations of numbers, letters or a mix of numbers and letters (now referred to as "items" instead of "numbers")
Maximum items to combine has been increased from 20 to 56
Has a new "Complete Set" option which can produce all x-number combinations from y numbers (eg: all 7-number combinations from 99 numbers)
Now allows duplicate items to combine (eg: 1,2,3,3,4,5,5,6,7, etc.)
Now allows entering of zeroes amongst the items to combine
