#! * a natural isomorphism $\rho_{a}: a \otimes 1 \cong a$,

#! * for all objects $a,b,c,d$, the pentagon identity holds:
#! $(\alpha_{a,b,c} \otimes \mathrm{id}_d) \circ \alpha_{a,b \otimes c, d} \circ ( \mathrm{id}_a \otimes \alpha_{b,c,d} ) = \alpha_{a \otimes b, c, d} \circ \alpha_{a,b,c \otimes d}$,
