Associated to a motive are vector spaces coming from cohomology of an algebraic variety. The dimension of these vector spaces is the **degree** of the motive.

For a hypergeometric motive with defining parameters $A=[a_1,\ldots,a_m]$, $B=[b_1,\ldots,b_n]$, the degree is the common value \[ \sum_{j=1}^m \phi(a_j) = \sum_{j=1}^n \phi(b_j)\] where $\phi$ is the Euler totient function.
