"So I converted each letter into a number between one and thirty-two, using the Baudot code. That gave me a long series of small numbers. But I wanted some way to convert all of the numbers in the series into one large number, just to see if it would contain any interesting patterns. But this was easy as pie! If the first letter is R, and its Baudot code is 01011, and the second letter is F, and its code is 10111, then I can simply combine the two into a ten-digit binary number, 0101110111. And then I can take the next letter’s code and stick that onto the end and get a fifteen-digit number. And so on. The letters come in groups of five—that’s twenty-five binary digits per group. With six groups on each line of the page, that’s a hundred and fifty binary digits per line. And with twenty lines on the page, that’s three thousand binary digits. So each page of the message could be thought of not as a series of six hundred letters, but as an encoded representation of a single number with a magnitude of around two raised to the three thousandth power, which works out to around ten to the nine hundredth power."
