Today's Agenda. The up-to-vertex-operations uniqueness of an ${\mathcal {A}}$ -valued algebraic knot theory.

Uniqueness up to vertex operations, vaguely.
The group ${\mathcal {A}}^{V}\subset {\mathcal {A}}(\theta )$ and its action on the set ${\mathcal {Z}}$ of ${\mathcal {A}}$ -valued algebraic knot theories.
An aside about trinions (also see 06-1350/Class Notes for Tuesday October 10).
The group ${\mathcal {A}}^{F}\subset {\mathcal {A}}(\uparrow _{2})$ and its action on the set of all associators.
An aside about braided $\theta$ -graphs:
