Mathews's Algorithm: Les Exercices de style (Raymond Queneau)

In Les Exercices de Style (Paris: Gallimard, 1947), Queneau relates the same banal incident on the Paris bus system ninety-nine times, each instance demonstrating a particular style. Below are four of the Exercices, each divided into nine parts. Mathews's Algorithm can be used to generate eight new versions of the incident: four by shifting the elements to the right, four by shifting them to the left.
