That's an array with about 72 billion elements (72,681,840,000 elements, to be exact) which'll take something like 280G of RAM to represent, if you're using 4 byte integers and a language with densely packed arrays. Perl isn't one of those languages. :)

Sounds like what you need here are sparse arrays or, if you need a fully populated array of that size, a lot of RAM...

I think you may find yourself going past normal limits with perl. You might want to look into perl's PDL extension to see if that might help you, but no matter how you look at it that's a darned enourmous array you're postulating.
