This mathematical construction when of order seven can be drawn in a rosette figure called "Victoria". The version of order three can be constructed with circles so that the central region is a Reuleaux triangle. In general, 
This mathematical construction when of order seven can be drawn in a rosette figure called "Victoria". The version of order three can be constructed with circles so that the central region is a Reuleaux triangle. In general, the construction of order n will partition the plane into 2^n (2 to the n) unique regions. Used in a seanon four episode of Numb3rs to narrow down a list of suspects, name this mathematical construction used to illustrate unions and intersections of sets.          |
