  In this paper we show how to combinatorically compute the rotation class of a
large family of embedded Legendrian tori in $\mathbb{R}^5$ with the standard
contact form. In particular, we give a formula to compute the Maslov index for
any loop on the torus and compute the Maslov number of the Legendrian torus.
These formulas are a necessary component in computing contact homology. Our
methods use a new way to represent knotted Legendrian tori called Lagrangian
hypercube diagrams.
