Resumen
We explore a three-dimensional counterpart of the Farey tessellation and its relations to Penner’s lambda lengths and SL2-tilings. In particular, we prove a three-dimensional version of the Ptolemy relation, and generalise results of Short to classify tame SL2-tilings over Eisenstein integers in terms of pairs of paths in the 3D Farey graph.
