- In theory yes, in practice no. Let me invent a notation. a&b means
-
- a^a^a^a ...... ^a
- \ /
- b times
-
- I submit that writing 10^100 & 10^100 is slightly tricky in standard
- notation. I believe Don Knuth invented something called arrow
- notation to describe really *huge* numbers like Skewes number.
-
- Consider another case. Let triangle x be x^x. Let square x be
- triangle triangle ..... x. Let circle x be square square ..... x
- \ x times / \ x times /
-
- circle 2 is a *large* number. It can't be written with standard
- notation. circle 10 is beyond the mind-pummling huge and moves into
- the brain squooshingly gigantic. Let us then pause to consider
- circle 10^100 & circle 10^100 which I modestly suggest be called
- frog's number.
-
- What I have always found... humbling is the word I want I guess
- is that however large these numbers may be, they aren't a patch on
- infinity. Even frog's number is *nothing* compared with some
- of the *really* big numbers out there.
