Is a tridecagon a Pierpont prime?

As 13 is a Pierpont prime but not a Fermat prime, the regular tridecagon cannot be constructed using a compass and straightedge. However, it is constructible using neusis, or an angle trisector. according to Andrew M. Gleason, based on the angle trisection by means of the Tomahawk (light blue).
