Distinctness conjecture for Chebyshev knot parametrizations

About 17 years old · traced to

Let TnT_n denote the degree-nn Chebyshev polynomial of the first kind. Let i,ji,j be relatively prime positive integers, and let k,ℓk,\ell belong to the semigroup denoted by ≪i,j≫\ll i,j\gg in the source. Distinctness conjecture. If k≠ℓk\ne\ell, then

(Ti,Tj,Tk)and(Ti,Tj,Tℓ)(T_i,T_j,T_k)\quad\text{and}\quad(T_i,T_j,T_{\ell})

define distinct knots. This is one of the conjectures suggested by the observed patterns for knots arising from reduced triples; the supplied text gives no resolution status.
