Combinations!

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.
