An iterative procedure for calculating a polyhedron with an extreme vertex arrangement allows one point to be fixed at any point on the sphere. In the applet, point A can be set at any point in the sphere. For orientation, you can set Check box "

**sphere**" - true. Click on the "**Click→Input,Initial settings**"-button and other starting points will be randomly set. Click the "**Start**"-button and wait for the iteration process to finish!
