(a) The perfect matchings for the dimer model corresponding to , with the external perfect matchings and the internal perfect matchings ; (b) The toric diagram of with the labeled multiplicity of GLSM fields. The master space is given by the perfect matchings modulo relations [14]. There is one relation among perfect matching and this gives the description of the master space as . We refer to [18, 19] for details on the Tiling construction and to [14] for a detailed discussion of this example.
