The pretzel knot $P(4, -3, 5)$ is not squeezed

Abstract

We prove that an infinite family of three-strand pretzel knots is not squeezed. In particular, we show that P(4,3,5)P(4, -3, 5) is not squeezed. This answers a question posed by Lewark (2024). Our proof is obtained by comparing the Rasmussen invariant with the qMq_M-invariant introduced by Iida and Taniguchi.
