Abstract
A frequent topic in the study of pattern avoidance is identifying when two sets of patterns are Wilf equivalent, that is, when for all . In recent work of Dokos et al. the notion of Wilf equivalence was refined to reflect when avoidance of classical patterns preserves certain statistics. We continue their work by examining des-Wilf equivalence when avoiding certain nonclassical patterns.
