- 2013, Brent Davis with Moshe Renert, The Math Teachers Know: Profound Understanding of Emergent Mathematics, New York, N.Y., Abingdon, Oxon.: Routledge, →ISBN Invalid ISBN, page 102:
- They [the students] also came upon new and unusual mathematical figures: the digon, a two-sided polygon on a spherical space, and the apeirogon, an open polygon with infinitely many sides […]. All these discoveries brought up even more questions. Is a circle a polygon? What makes an octagon an octagon – its eight vertices, its eight sides, or both? Can a polygon cross itself? Does a polygon need to be closed?
- (graph theory) A pair of parallel undirected edges in a multigraph.
- (graph theory) A pair of antiparallel edges in a directed graph.
