Abstract
We develop combinatorial tools to study the relationship between the Stanley depth of a monomial ideal and the Stanley depth of its compliment, . Using these results we are able to prove that if is a polynomial ring with at most 5 indeterminates and is a square-free monomial ideal, then the Stanley depth of is strictly larger than the Stanley depth of . Using a computer search, we are able to extend this strict inequality up to polynomial rings with at most 7 indeterminates. This partially answers questions asked by Propescu and Qureshi as well as Herzog.
