==Real Clifford algebra R<sub>3,1</sub>== Developed by [[Ettore Majorana]], this Clifford module enables the construction of a [[Dirac equation|Dirac-like equation]] without complex numbers, and its elements are called Majorana [[spinors]]. The four basis vectors are the three Pauli matrices and a fourth antihermitian matrix. The [[sign convention|signature]] is (+++β). For the signatures (+βββ) and (βββ+) often used in physics, 4Γ4 complex matrices or 8Γ8 real matrices are needed.
