- I already described this notation in a previous thread. It is
- in Philip Davis's LORE OF LARGE NUMBERS, except that the circle
- should be a pentagon. Counting "triangle, square, circle" is like
- counting "one, two, and a heap". What you are calling "circle 2"
- is the Mega.
-
- As I noted in my post, "circle" isn't all that powerful an
- operator. This is because "triangle triangle x" is just
- (x^x)^(x^x) and not x^(x^(x^x)).
-
- Actually, I think I somewhat underestimated it before, but
- right now I still think "circle 2" is less than a tower of
- 257 256's, which is writable. ( Before I had the tower growing
- by zero per iteration instead of one per iteration. )

-
- Yeah, like for example the Moser ( 2 in a Mega-gon ). But you're
- right of course. What about a Moser in a Moser-gon! and so on.
- It's all just counting.
