The Arithmetic of Points on a Conic and Projectivities

by H. S. M. COXETER, GEORGE BECK


ABSTRACT: H. S. M. Coxeter wrote several geometry film scripts that were produced between 1965 and 1971. In 1992, Coxeter gave George Beck mimeographs of two scripts that had not been made. Beck wrote Mathematica code for the stills and animations. This material was added to the third edition of Coxeter’s The Real Projective Plane. This article updates the Mathematica code.
