Conway, Doyle, Gilman, Thurston; The Geometry Center  
Topology is the theory of shapes that are allowed to stretch, compress, flex and bend, but without tearing or gluing. For example, a square is topologically equivalent to a circle, since a square can be continously deformed into a circle. As another example, a doughnut and a coffee cup with a handle for are topologically equivalent, since a doughnut can be reshaped into a coffee cup without tearing or gluing. Which of the capital letters are topologically the same, and which are topologically different? How many topologically different capital letters are there?
