A bstract The dynamical content of equations resulting from rank-two covariant derivatives in B 2 Coxeter theory in AdS 4 are analyzed in terms of σ − -complexes. Primary fields and gauge-invariant differential operators on primary fields are classified for ( adj ⊗ adj ) one-form fields ω and ( tw ⊗ adj ) zero-form fields C . It is shown that one-forms ω in the ( adj ⊗ adj ) sector encode symmetric massless fields and partially massless fields of all spins and depth of masslessness. Gluing of the one-form module to the zero-form modules at the linear vertices is studied.
