“…Let Φ = T 1 T 2 T 3 . It follows from the computation of the generic degrees and the character table of H q (w) in [BMa,5.A] that a representation is special if (and only if) the elements {(T i ) i=1,2,3 , (T i T j ) i=1,2,3, j=1+(i mod 3) , (Φ i ) i=1,2,3 } have trace zero on it. The quadratic relations show that B = {(T i ) i=1,2,3 , (T i Φ) i=1,2,3 , (Φ i ) i=1,2,3 } generates the same subspace of H q (w) as these elements.…”
