ergmx.l3xax(attr, levels=None)

L3XAX: three-paths of an X-tie, an A-tie and an X-tie, the sum over A-ties of the product of their endpoints’ X-degrees (so closed paths, the TXAX triangles, count too, as Wang et al. say: “the TXAX configuration is also part of L3XAX”). In directed networks, over A-arcs (MPNet’s directed L3XAX). For two-level (multilevel) networks, as MPNet (Wang et al. 2013): the levels are the values of the vertex attribute attr, A and B (levels=(A, B), or the attribute’s two values, sorted); A-ties are within A, B-ties within B, X-ties between them. Undirected networks.
