“…Specifically E 12 , E 23 , E 31 are spins about x 1 , x 3 , x 2 accompanied by parities E 34 , E 24 , E 14 that are rotations about x 4 which reflect apin, while E 05 is a coordinate in isospace carrying charge. In this way equation 1covers the 12 vertices representing the nucleons and anti-nucleons on the outer shell of Fig.1 that are supposed to survive when the 6d projective space CP 3 of E 6 compactifies to a 3d projective space [5].…”
