Twisted torus knots with Horadam parameters

Sangyop Lee has done much work to determine the knot types of twisted torus knots, including classifying the twisted torus knots which are the unknot. Among the unknotted twisted torus knots are those of the form [Formula: see text], where [Formula: see text] is the [Formula: see text]th Fibonacci number. Here, we consider twisted torus knots with parameters that are defined recursively, similarly to the Fibonacci sequence. We call these Horadam parameters, after the generalization of the Fibonacci sequence introduced by Horadam. Here, we provide families of twisted torus knots that generalize Lee’s work with Horadam parameters. Additionally, we provide lists of primitive/primitive and primitive/Seifert twisted torus knots and connect these lists to the Horadam twisted torus knots.
