The Chen–Gackstatter surfaces, constructed in 1982, are a family of complete orientable minimal surfaces of that generalize Enneper's minimal surface by adding handles that increase its topological genus or by adding -fold dihedral symmetry. In cases with genus values greater than one, the formulas for the surfaces involve generalized hypergeometric functions.
