We explore a method of encoding secret messages using factoradic numbering of
permuted lists of text or numeric elements. Encoding and decoding methods are
provided, with code, and key aspects of the correctness of the methods are
formally proven. The method of encoding is simple and provides a working
example of using textual and numeric lists as a stenagographic channel. Given
the ubiquity of lists, such channels are already present but are often unused.
