Notation 3.1. We will write

$$\underline{\hom}(-,-)=\underline{\hom}_{s{\mathcal{S}\textup{et}}}(-,-):(s{\mathcal{S}\textup{et}})^{op}\times s{\mathcal{S}\textup{et}}\rightarrow s{\mathcal{S}\textup{et}}$$

for the internal hom bifunctor in $s{\mathcal{S}\textup{et}}$ (relative to its cartesian symmetric monoidal structure).
