The challenge is to come up with a mathematical way to generate each character of the exact string:
(Capital letter, comma, exclamation mark.)
But you can't use any strings, arrays, or equivalents, to contain the data of the text. You must derive the characters by mathematical means.
So just a list or array of characters or ASCII codes or numbers trivially offset or inverted or shifted does not count. Nor does downloading it from an external resource or taking user input. Nor does starting with a large number which is just each ASCII codes shifted and ORed together, etc.
You can use any programming language, any mathematical functions, math libraries, etc.
The characters can of course be strings as you generate them.
Think of something like generating the digits of π.
The winner shall be the one with the most cleverness and/or elegance. The relevant weightings of cleverness and elegance are up to your peers, for the winner shall be decided by voting. (Finding a loophole in my poor problem statement shall not be regarded as clever d-:)
I think you can get the jist so don't cheat and if I should make it clearer or close some loopholes then please comment.
