this is nowhere near the largest, mine is 860 digits and this one is only 255
or 1129834378225399760317063170636377458663729448371904881513577643245534731167933... This is only a preview of the 80 out of 2,089,878 digits it has!
@Sergeant_Starfruit 2nd comment: I already put in the description that it counts to a quattuoroctogintillion. Besides, I found larger, The 10000th step of the Fibonacci and the Googolplex.
@NicNamSam The counters aren't made out of gravity breakables.
Whoops, I lightning'd it. Oh, whoops, now I gbombed it.
Wait, this is bigger... 3###3= 3##(3##3) = 3##7,625,597,484,987 =3#(7,625,597,484,987#7,625,597,484,987) (this expression is too large to express as a number) LOL!
But this is the largest I could find: quattuorquinquagintilliard, 327 zeros!
Also, "quattuoroctogintillion" is what this is called!
