[en] It is shown how to write the Susskind fermionic action in the Lagrangian formalism explicitly in terms of flavour Dirac fields defined on hypercubes in position space. The remnant continuous global symmetries may be identified with a U(1)sub(V) x U(1)sub(A) group, where the axial symmetry is flavour non-singlet. The formalism is applied to the calculation of the decay constant of the pseudoscalar Goldstone boson in the strong coupling limit, where we have previously shown that the U(1)sub(A) symmetry is spontaneously broken
