We reconsider the fundamental question regarding the number of elementary particles in a minimally extended standard model. The main conclusion is that since the dimension of E-infinity spacetime is resolution dependent, then the number of elementary particles is also resolution dependent. For D
=10 of superstrings, D
=11 of M theory and D
=12 of F theory one finds N(SM) equal to (6)(10)=60, (6)(11)=66 and (6)(12)=72 particles, respectively. This is in perfect agreement with prediction made previously by Mohamed Saladin El-Naschie and Marek-Crnjac.
