We here classify those of width two. There are 2 two-parameter families that project to the second dilation of a unimodular triangle, 29+23 one-parameter families of them that project to hollow 3-polytopes, and 2282 individual ones that do not.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Classification of empty polytopesEmpty simplicesLattice polytopesjournal articleopen access10.1016/j.endm.2018.06.027
