Binary Icosahedral Group, In fact, there is no subgroup of 2 I isomorphic to I.

Binary Icosahedral Group, Abstract. In previous papers I have shown how the binary tetrahedral group gives rise to all the necessary ingredients for a non-relativistic model of quantum mechanics and elementary particles, and how a In mathematics, the binary icosahedral group 2I or 2,3,5 is a certain nonabelian group of order 120. In fact, up to isomorphism, the binary icosahedral group is the unique finite group of order 120 which is a perfect group. In fact, there is no subgroup of 2 I isomorphic to I. It's called the binary icosahedral group. There are exactly three finite subgroups of SU(2) that act irre-ducibly in the spin 1 representation, namely the binary tetrahedral, binary octahedral and binary icosahedral groups. The binary icosahedral group, denoted \\(2I\\) or \\(\\widetilde{A_5}\\), is a nonabelian finite group of order 120 that serves as the universal (double) cover of the icosahedral rotation group \\(I \\cong A_5\\), the alternating group on five elements. It's also not A 5 × ℤ /2. In addition, we show that the binary icosahedral group in H is the set of vertices of Abstract.
