On the Subject of Graph Identification

No, not XY plots. What are you, twelve?

The five bottom buttons on the module are labeled with graphs, the vertices represented by the vertices of a regular decagon and the edges being represented by straight lines connecting them.

You are in one of the graphs on the buttons. The display is labeled with the name of the vertex you’re in (a letter from A-J), and the three lettered buttons have the names of the three vertices connected to it by edges. Pressing a button labeled with a vertex will take you to that vertex. The vertex names are randomly assigned and consistent for that module.

Press the button labeled with the graph you’re in. Pressing an incorrect button will strike, but will not reset the module.
