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

Can feel it coming together.. Slowly but Surely

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.

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.
