 2013, Brent Davis; Moshe Renert, The Math Teachers Know: Profound Understanding of Emergent Mathematics, New York, N.Y.; Abingdon, Oxon.: Routledge, →ISBN, page 102:
 They [the students] also came upon new and unusual mathematical figures: the digon, a twosided 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?
