Graham's Number

Has anybody any ideas on how to find out the digits?


Can feel it coming together.. Slowly but Surely smile

Re: Graham's Number

Hi David;

Ramsey theory and numbers are the toughest. To give you an idea of what you are asking I spent a long time trying to get just the front digit of the power tower:

9^(9^(9^9))

And that tower is immeasurably tiny next to Grahams number.


In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Graham's Number

Hi Bobby

Wow, I thought it would be very complicated. I watched a documentary a while ago on Infinity and Ronald Graham came on discussing how he decided one day to stop being a Circus artist and become a Mathematician and he explained how he came up with them number.

Are the carrats in your 9^(9^(9^9) Knuth notation?

Hi Dave;

No, that represents regular exponentiation:



I didn't see that documentary.
