Subdivided expanders and counterexamples to the Tree Product Conjecture

Distel, Gollin, Harvey, Hendrey, Hickingbotham, Mohar and Wood (2023) conjectured that graphs of degree-$d$ polynomial growth can be embedded into the strong product of $d$ trees, each with linear growth, and a constant-size complete graph. Very recently, the case $d = 4$ of the conjecture was disproved by Illingworth,...
