The two-particle reduced density matrix p2 is analyzed for a system of electrons described by the BCS ground state. The existence of off-diagonal longrange order in pZ is demonstrated by explicit calculation of its matrix elements. It is shown that pz has one eigenvalue proportional to N where N is
