Pappus's Theorem deals with collinearity in this polygon, and the regular variety of this polygon is an orthogonal projection of a 5-simplex. The nth number of this type is equal to two times n squared minus n, and it has the most sides of any regular polygon which can (*) tile the plane. For regular polygons of this type, the longest diagonal is twice as long as a side, and the exterior angle is 60 degrees, meaning that each interior angle is 120 degrees. For ten points, give the general name for a six-sided polygon.
