For a grading-restricted vertex superalgebraVand an automorphismgofV, we give a linearly independent set of generators of the universal lower-bounded generalizedg-twistedV-moduleconstructed by the author in Huang (Commun Math Phys 377:909–945 (2020)). We prove that there exist irreducible lower-bounded generalizedg-twistedV-modules by showing that there exists a maximal proper submodule offor a one-dimensional spaceM. We then give several spanning sets ofand discuss the relations among elements of the spanning sets. Assuming thatVis a Möbius vertex superalgebra (to make sure that lowest weights make sense) and thatP(V) (the set of all numbers of the formforsuch thatis an eigenvalue ofg) has no accumulation point in(to make sure that irreducible lower-bounded generalizedg-twistedV-modules have lowest weights). Under suitable additional conditions, which hold when the twisted zero-mode algebra or the twisted Zhu’s algebra is finite dimensional, we prove that there exists an irreducible grading-restricted generalizedg-twistedV-module, which is in fact an irreducible ordinaryg-twistedV-module whengis of finite order. We also prove that every lower-bounded generalized module with an action ofgfor the fixed-point subalgebraofVundergcan be extended to a lower-bounded generalizedg-twistedV-module.
