**Write/describe the largest finite number you possibly can in one post.**You may use any amount of functions, numbers, or operations you know of or can come up with. As long as your number is unambiguously expressed, it counts.

**Please do not use any references (google/books/calculators/etc.)**Just your noggin' if you please! Of course you can work stuff out on a piece of paper if you need, but I'd prefer to see what people come up with without consulting any references outside their brain.

**Please post your response without reading any of the other replies in this thread**

This is an interesting experiment I recently did with one of my classes and I'd love to see what people come up with here.

After this goes on for awhile, I'll post some of the more clever answers my students gave.
