Did you know, for example, that a 10,000sided figure is a "myriagon"? We also have a list of names for polygons but ours only goes up to 20 sides. Now here's a question for you: what threedimensional figure, that you can make with paper, scissors and a bit of tape, has only one side and only one edge? Stephen La Rocque.>
