Can you figure this out?

Heh, I was bored (done my calculus homework... ), so I thought up some crazy stuff... what do these strings of numbers have in common, and where do they come from?

Can you figure this out?

is each line a number? or is it one big number?

[Feztaa]

is each line a number? or is it one big number?

Each line is a section of a larger number, though the lines are non-contiguous

[Feztaa]

Ok, I should be more specific.

I started with one very large number, then wrapped it at 72 chars. Then I grepped through for a certain string and came up with this.

1) What did I grep for?

and

2) What was the original number? (you can describe it instead of posting the entire thing).

You grepped for '1337'

[Feztaa]

That was faster than I thought. Maybe I'm just predictable

What was the original number, mr smartypants?

I ain't got no idea. I would say probably the factorial of a number. But the number is not 1337

Can you give a clue?

[Feztaa]

Yep, it's a factorial, and it's been posted here before (I think). If it hasn't been posted here before, then this is +1 of a number that has been posted here before.

factorial of 65,535? 65,536?
