User blog:WaxPlanck/The March Towards G1

This is the computational march towards the first layer of Graham's number. Though getting to this number is probably impossible with mortal technology (I am using the same code as the pentation, it is just even crazier)

1.5             25 1.6             472 1.7             156611880789970439883424738458273 1.8             >4*(10^450) (pending result, GP is not very accurate with approximation here)

Getting to this number is (on our scales) almost infinitely harder than the other 2 pentated to 4 (or 2 tetrated to 65536, the two numbers are equivalent in size and value) but almost infinitely easier than the next layer by a larger amount than either number being uncomputable.
