Working on a little project, and I need help coming up with as many different ways of representing the number 42 as possible (avoiding simple base-n representations [except of course for decimal and binary]). So far I've come up with decimal, binary, roman numerals, printing out 42 dots or slashes, "6 X 7", "forty-two", "quarante deux", "42/1","2x3x7" [prime factors], and "41++".
What are other interesting and possibly funny ways to represent this number?
Hint: We are going from a book, not at a math one. Though, to be fair, it is where binary came from. Well, Leibniz notes the book as inspiration. He came up with his idea before seeing the book. But the book predates him by a little bit.
