A hidden Condorcet domain in Loday's realisation of the associahedron
arXiv:2501.13374
Abstract
We prove that Loday's polytopal realisation of the nth Tamari lattice T_n, called associahedron, has 2^{n-1} common points with the permutohedron, which form a maximal never-middle (symmetric) Condorcet domain.
