    Anonymous Monk,
    What Corion didn't explicitly state is that this is just base conversion. Just as in base 16, we let the letters A-F represent 10-15, Corion is letting A, C, T, G stand for values. It is then a fairly trivial math process to convert between bases. Corion shows one way but it isn't the only one.

    Cheers - L~R

    Paper? You mean like a white paper? No, it's too basic for that. It's standard introductory algebra, the sort of thing you have to be able to do in your sleep before you can take any higher math.
