Crossing-number conjecture for consecutive Chebyshev degrees

About 17 years old · traced to

Let TnT_n denote the degree-nn Chebyshev polynomial of the first kind. For an odd integer i≥3i\ge 3, the consecutive-degree crossing-number conjecture. The parametrization

(Ti,Ti+1,Ti+2)(T_i,T_{i+1},T_{i+2})

parametrizes a knot with crossing number ii. The source says this pattern has been verified through a finite range in a related family but reports no proof for all values, and presents the assertion as an open problem.
