The coherence theorem and strictification theorem for symmetric monoidal categories may each take several forms.
Every diagram in a free symmetric monoidal category made up of associators and unitors and symmetries (braidings), and in which both sides have the same underlying permutation, commutes.
The free symmetric monoidal category on some given data is equivalent to the free symmetric strict monoidal category on the same data.
Every symmetric monoidal category is equivalent to an unbiased symmetric monoidal category?.
Every symmetric monoidal category is symmetric-monoidally equivalent to a symmetric strict monoidal category.
The forgetful 2-functor has a strict left adjoint and the components of the unit are equivalences in .
Note that in a symmetric strict monoidal category, the associators and unitors are identities, but the symmetry is not in general.
