This paper presents a superunified model in six dimensions using the superalgebra SU(5|1) with the vector and Higgs mesons being the various components of the gauge fields. These are fixed by the principle of infinitesimal gauge invariance to give the standard symmetry-breaking mechanism. Superheavy vector-meson masses are obtained by an additional scalar matter 24-plet. Fermions are placed in the 10 ⊕ 5 representation, and their masses examined; the theory is shown to be anomaly free.
