We include Pati¡¯s supergravity based preon model in this work and compare the preon interactions of his model to ours. Based on preon-string symmetry comparison and preon phenomenological results, we conclude that the fundamental particles are likely preons rather than standard model particles. %K Topological Field Theory %K Chern-Simons Theory %K Supersymmetry %K String Theory %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=130231
