Historical Note on $450$ Factorial

The factorial of $450$ was calculated by Horace Scudder Uhler in the $1950$s without the aid of a computer.

As he found it had exactly $1001$ digits, he called it the Arabian Nights factorial:

The first digit of $450!$ falls in the $1001$th place to the left of the decimal point ... this number may be fancifully dubbed the Arabian Nights' Factorial.
