Knot quandles distinguish Suciu's ribbon knots

Abstract

The knot quandle is an invariant of $n$-knots. In this note, we study the knot quandles of Suciu's ribbon $n$-knots, an infinite family of knots with isomorphic knot groups. We prove that their knot quandles are mutually non-isomorphic. Furthermore, we compute types of these quandles.
