davido's advice leads to the following exercise: write a script that takes a list of file names, counts the lines in each file and calculates the number of possible combinations (without creating the combinations, of course). (Nothing against pencil and slide rule, but this is a Perl community...) Once you have the result, we can continue the discussion.
