In Table 8.8, we used p o , p 1 , p 2 , 1 ,

In Table 8.8, we used p_o, p₁, p₂, µ₁, µ₂ , µ₃ as the names of the 6 elements of S₃. Some authors use the notations ∈, p, p², ∅, p∅, p²∅ for these elements, where their ∈ is our identity p₀, their p is our p₁, and their ∅ is our µ₁. Verify geometrically that their six expressions do give all of S₃.
