In 1970 he published a book, Adventures among the toroids. A study of orientable polyhedra with regular faces, in which he discussed what are now called Stewart toroids. The book was handwritten in calligraphy with many formulas and illustrations. Like the Platonic solids, Archimedean solids, and Johnson solids, the Stewart polyhedra have regular polygons as faces. The first three categories are all convex, whereas Stewart toroids have polygonal-faced tunnels. Selected publications
