What do you mean by "getting to G1"?

If you are refering to actually calculating all the decimal digits, then it is definitely (not "probably") impossible due to the simple fact of these digits not fitting into the observable universe. Even 3↑↑↑↑2 is already equal to triri, which is a power tower of over 7 trillion 3's.

If you are only interested in a base-10 high-precision approximation, that is actually fairly easy to accomplish:

g1 = Grahal = 10↑↑↑(10↑)76255974849836.00225...x103638334640023

The final number in scientific notation would be equal to 37625597484987x(log103) to a precision of over 3 trillion digits.
