The trimmed directed power graph of dihedral group:D8.

The file was created using Graphviz. The generating code is given below:

digraph G{       rankdir = "BT"; e[label="Identity element"]; c[label="a^2, non-identity central element"]; x[label="x, reflection"]; ax[label="ax, reflection"]; a2x[label="a^2x, reflection"]; a3x[label="a^3x, reflection"]; a[label="a, rotation of order four"]; a3[label="a^3, rotation of order four"]; a -> c -> e;       a -> a3[style=dotted]; a3 -> a [style=dotted]; a3 -> c;       x -> e;        ax -> e;        a2x -> e;        a3x -> e; }
