Abstract
Defant, Engen, and Miller defined a refinement of Lassalle's sequence by considering uniquely sorted permutations of length whose first element is . They showed that each such sequence is symmetric in and conjectured that these sequences are unimodal. We prove that the sequences are unimodal.
