M.C. Escher's print Circle Limit IV is the last of his four " Circle Limit " patterns. There are two questions one can ask about the symmetry of Circle Limit IV. First, what is the correct orientation in which to display the print? Second, what is the symmetry group of the pattern? We answer those questions and show some new patterns related to Circle Limit(More)
Peripheral nerve hemorrhage has rarely been reported with idiopathic thrombocytopenic purpura (ITP). We describe a patient with severe ITP who developed mononeuropathy multiplex. At autopsy, multisystem hemorrhages were found, including intraneural hemorrhage, without evidence of extraneural hematoma. ITP represents an unusual cause for clinical(More)
