Abstract
We prove a combinatorial identity, which implies a connection between an identity of Milne and an identity of Glass and Ng concerning the hook length formula. As applications, we obtain some new formulas on partitions, factorial numbers, rising factorial numbers, falling factorial numbers, and Catalan numbers.
