Okay, what about 4->6->8->9? This is geater than Graham's Number! big_smile

For the 4!!!!!, you'd need to use brackets to show what you meant.

4!! just means 4*2. 5!! is 5*3*1, and so on.

Double-factorials are less than their single-factorial counterparts (except with 0, 1 and 2)

I think Flowers4Carlos's version would be higher, but that's just a guess.

Ginormous numbers. Good link Ganesh.

Conclusion: we need to set a limit on the operators then, or you could just use 4^^^^^..., or even 4!!!!...

I think 4^^^6^^^8^^^9 is a much bigger number. You can use any number of '^' and keep increasing the number. There's no end to it.
If you are interested in knowing what x^^^y or x^^^^y is, go to this page.

Sorry, had to remove your address for "internet safety" reasons.

9864! (that is 9864 factorial ... 70! has about 100 digits, 9864! will possibly have tens of thouands of digits)

But that may be cheating ...

uh oh!  you are not allowed to post your email.  you gotta send in your birth certificate to rod proving you are of a certain age first wink

and as for your query.... i guess it would be (4!)^(6!)^(8!)^(9!)

my calculator can't even handel 2^9!

Please answer to my email address : [snip]
