A new lattice model is presented for correlated electrons on the un­restricted 4^{L}-dimensional electronic Hilbert space ⨁^{L}_{n=1}C^{4} (where L is the lattice length). It is an extension of the supersymmetric t-J model. The new model has gl(2|1) supersymmetry and contains one symmetry-preserving free real parameter α which has its origin in the one-parameter family of inequiv­alent typical 4-dimensional irreps of gl(2|1). When α = 0, the model reduces to the supersymmetric t-J model.
