We use the methods of the CALKUL Collaboration to calculate the differential cross section for {ital e}{sup +}{ital e}{sup {minus}}{r arrow}{mu}{sup +}{mu}{sup {minus}}+2({gamma}) near the {ital Z}{sup 0} resonance. An {ital explicit} complete formula for the cross section is obtained. The formula is checked against a leading-log approximation and against one obtained by spinor techniques. Applications to high-precision {ital Z}{sup 0} physics are discussed.
