Enumeration of permutations avoiding a triple of 4-letter patterns is all done
David Callan, Toufik Mansour, Mark Shattuck
This paper completes a project to enumerate permutations avoiding a triple T of 4-letter patterns, in the sense of classical pattern avoidance, for every T. There are 317 symmetry…

Enumeration of small Wilf classes avoiding 1342 and two other -letter patterns
David Callan, Toufik Mansour
This paper is one of a series whose goal is to enumerate the avoiders, in the sense of classical pattern avoidance, for each triple of 4-letter patterns. There are 317 symmetry cla…

Enumeration of small Wilf classes avoiding 1324 and two other 4-letter patterns
David Callan, Toufik Mansour
Recently, it has been determined that there are 242 Wilf classes of triples of 4-letter permutation patterns by showing that there are 32 non-singleton Wilf classes. Moreover, the…
