We describe a random distribution on the spanning trees of bounded-bandwidth graphs such that each edge has bounded expected stretch, along with several related results for other kinds of graph widths.

The \(n\)-disc \(p\)-peg Hanoi graphs have treewidth within a polynomial factor of \(n^{p-1}\). In a follow-up paper, "On the expansion of Hanoi graphs", we eliminated the polynomial factor.

On the expansion of Hanoi graphs.
D. Eppstein, D. Frishberg, and W. Maxwell.
arXiv:2510.18010
Discrete Mathematics & Theoretical Computer Science 28 (2): 31:1–31:18, 2026, doi:10.46298/dmtcs.16770.

In a previous paper, "On the treewidth of Hanoi graphs", we showed that \(n\)-disc \(p\)-peg Hanoi graphs have treewidth within a polynomial factor of \(n^{p-1}\). Here we consider expansion instead, and prove that both it and the treewidth are \(\Theta(n^{p-1})\).
