From a reader: “How about (9!)^(9!)^(9!)?”
Yep, that beats my footling little 9^9^9. Must have forgotten to take my
math pill this morning.
The number of digits in (9!)^(9!)^(9!) is very large. It starts
“3,584,483,721,901,355,569,082,540,344,914…” and continues for another
2,017,497 digits.
That’s not the number: that’s THE NUMBER OF DIGITS IN THE NUMBER.
