We report the preparation of almost phase pure (T10.sPbo.s)Sr2Ca2Cu3Og, which is characterized by high temperature superconductivity with T¢onset= 130 K, Tcmidpoint= 124 K, Tczero= 122.5 K as measured by electrical resistance, and a diamagnetic onset temperature, Tcm~ of 124 K determined by DC magne
