Layer sequences of hyperbolic tessellationsLayer sequence of a pentagonal tessellation
Each pentagon is regular, with geodesic sides and an angle of 90° at each vertex. The layer sequence has the generating function 
and is just the walk length sequence of the following directed and edge-weighted graph, starting from the circled vertex on the left 
Layer sequence of the modular tessellation
Each triangle has a cusp at infinity and an angle of 60° at the other 2 vertices. The layer sequence has the generating function 
and is just the walk length sequence of the following directed and edge-weighted graph, starting from the circled vertex on the left
