  We describe the quantum flat universe in QRLG in terms of states based at
cuboidal graphs with six-valent nodes. We investigate the action of the scalar
constraint operator at each node and we construct proper semiclassical states.
This allows us to discuss the semiclassical effective dynamics of the quantum
universe, which resembles that of LQC. In particular, the regulator is
identified with the third root of the inverse number of nodes within each
homogeneous patch, while inverse-volume corrections are enhanced.
