Algorithmic coincidence classification of mesh patterns
Christian Bean, Bjarki Gudmundsson, Tomas Ken Magnusson +1
We review and extend previous results on coincidence of mesh patterns. We introduce the notion of a force on a permutation pattern and apply it to the coincidence classification of…

Automatic discovery of structural rules of permutation classes
Christian Bean, Bjarki Gudmundsson, Henning Ulfarsson
We introduce an algorithm that conjectures the structure of a permutation class in the form of a disjoint cover of "rules"; similar to generalized grid classes. The cover is usuall…
