Derby–Klassen compact mapping code
Derby–Klassen compact mapping code is represented at T1 by one finite two-face open patch with six vertex qubits and one odd-face qubit. The deterministic constructor validates the binary symplectic quotient and derives the displayed operator-incidence view from those same checks. Decoder, operation, relation, and realization facets remain unsurveyed.
