The Lattice of Definable Equivalence Relations in Homogeneous $n$-Dimensional Permutation Structures

[摘要] In Homogeneous permutations, Peter Cameron [Electronic Journal of Combinatorics 2002] classified the homogeneous permutations (homogeneous structures with 2 linear orders), and posed the problem of classifying the homogeneous $n$-dimensional permutation s
