Abstract

We construct an explicit algebraic realisation of three fermion generations within a single Clifford algebra, transforming under the full Standard Model SU(3)C× SU(2)L× U(1)Y gauge group, in which an intrinsic S3 family symmetry permutes three algebraically distinguished but gauge-equivalent fermion sectors without replicating the gauge bosons. Fermionic states are represented by minimal left ideals of the complex Clifford algebra ℂℓ(10), while the three-generation structure arises from an embedded discrete S3 symmetry acting on the space of algebraic spinors. The Standard Model gauge generators are identified as elements commuting with this S3 action and act on physical states via the adjoint (commutator) action. The resulting spectrum reproduces the correct Standard Model quantum numbers for three linearly independent generations of fermions.
