  In the year 2000, Eric Egge introduced the generalized Terwilliger algebra
$\mathcal T$ of a distance-regular graph $\Gamma$. For any vertex $x$ of
$\Gamma,$ there is a surjective algebra homomorphism $\natural$ from $\mathcal
T$ to the Terwilliger algebra $T(x)$. If $\Gamma$ is complete, then $\natural$
is an isomorphism. If $\Gamma$ is not complete, then $\natural$ may or may not
be an isomorphism, and in general the details are unknown. We show that if
$\Gamma$ is a hypercube, then the algebra homomorphism $\natural:\mathcal T \to
T(x)$ is an isomorphism for all vertices $x$ of $\Gamma$.
