{synonym}
For diagram inclusion $\mu\subseteq\lambda$, the skew Young diagram $\lambda/\mu$ consists of the cells of $\lambda$ outside $\mu$. Diagram inclusion is not the <dominance order on partitions>. Edge adjacency defines its connected components, and a connected skew diagram without a $2\times2$ square is a <rim hook>.
