Definitions and general methods for construction and classification are outlined. For one infinite family of combinatorial surfaces its dihedral symmetry is used to construct all embeddings and to characterize the possible congruence classes of the control triangle. The investigation is motivated by problems in rigid origami. Keywords: Simplicial surfaces, polytopes, moduli spaces, origami, tesselations, symmetry.
