Two Examples of Unbalanced Wilf-Equivalence

with Alex Burstein

We prove that the set of patterns \(\{1324,3416725\}\) is Wilf-equivalent to the pattern \(1234\) and that the set of patterns \(\{2143,3142,246135\}\) is Wilf-equivalent to the set of patterns \(\{2413,3142\}\). These are the first known unbalanced Wilf-equivalences for classical patterns between finite sets of patterns.
