N2 - Conventionally we collect electron and up/down quarks (u, d) ⊕ (νe, e) to form unified generations, and collect the left-handed and the right-handed fermions of the same flavors (νe, e) ⊕ over(e, ̄). We can alternatively have a contorted multiplet, made by pairing different quarks and leptons, like (u, d) ⊕ (νμ, μ) or (u, d) ⊕ (ντ, τ), and/or between different left- and right-handed fermions to (νe, e) ⊕ over(μ, ̄), etc. These can suppress proton decay, due to its high flavor dependence, while having the correct fermion masses.
