Research summary
The paper proves the structural equivariance and singlet-eigenvalue parts of an AKLT transfer-matrix conjecture for arbitrary self-conjugate virtual irreps. For the wedge family it reduces the spectrum to a Johnson scheme and solves the resulting triangular system by Riordan inversion, yielding closed binomial expressions.
