Inspired by the infamous Lynz , I hereby define a googolism that changes with time which I'll call Psi's Ever-Growing Googolism (PEGG):

1. On May 8, 2017, we set:

X = 0.00

Y = "E"

Z = 0.01


PEGG = <the letter stored in Y>X = E0.00 = 1

2. Every day after that, we follow this algorithm:

(a) We take the hundredths digit of the Dow Jones Industrial Average at the end of the previous day and call it n. If n=0 then we set n=10. For weekends and other non-commerence days, we use the n from the previous day.

(the reason for using the Dow Jones is to have a public source of pseudorandom numbers).

(c) X+(n2Z) → X

(d) int(<the letter stored in Y>X) → PEGG

(for example, if Y is the letter E and X=3.1 then we'll set the new value of PEGG to int(E3.1) = 1258.

(e) If X>10 than we also do the following:

(e-1) Increment the letter in Y by one (so if it was "E", it will now be "F")

(e-2) Convert the new value of PEGG to the form <the new letter in Y>m

(e-3) int(mK)/K→X

(e-4) 0.7xZ→Z

(e-5) 10K→K

And that's it.

Anyone wants to try and guess when PEGG will first surpass a googol?

EDIT: I've changed the definition abit so the numbers will be a little rounder and easier to work with
