• Turn on node numbers (in addition to keypoint and area numbers) using Utility Menu > PlotCtrls > Numbering
• Display elements and nodes together: Utility Menu > PlotCtrls > Multi-Plot Ctrls > OK. Leave only Nodes and Elements turned on and click OK. Select Utility Menu > Plot > Multi-Plots.
• Zoom into the bottom-center of the model as in the snaphsot below. At the bottom of the symmetry plane, you should notice that there are actually two nodes, 2 and 172.

(Note that your node numbers may be different from mine since numbering can vary on different computer systems.)
