This question is related to the question of drawing a [combinatorial 3-configuration of points and lines with straight lines][1]. We only relax the condition and admit drawings with pseudolines. Let us call a combinatorial configuration that can be drawn with pseudolines **topologically realizable**. This notion is readily carried over to the corresponding Levi graph of the configuration. Namely, the graph is topologically realizable if it is the Levi graph (=incidence graph) of a configuration of points and pseudolines. It is known that neither the Fano plane (7<sub>3</sub>) nor the Moebius-Kantor configuration (8<sub>3</sub>) are topologically realizable. Among the ten (10<sub>3</sub>) combinatorial configurations nine are (geometrically) realizable and one is only topologically realizable. I would like to know what is known about the status of the following complexity decision problem. >**Input:** Cubic connected bipartite graph G of girth at least 6. >**Question:** Is G topologically realizable? The book "Configurations of Points and Lines" by Branko Grunbaum discusses this problem as a classification problem but not as a complexity problem.
