I think you're still working on this, is that right @frankiegillis ? |

Yes, currently benchmarking the two methods for computing the orbit of a 2-edge: Method 1 (Compute the orbit directly) against Method 2 (Compute the stabiliser). Here are some plots. To benchmark, I generated random digraphs using RandomDigraph using the edge probability as a way of controlling the average orbit length. It turns out that Method 1 is almost always faster, apart from when tested on the list of named digraphs when it is much slower. I don't think this is a case of Method 2 being fast, but Method 1 being unusually slow. I'm looking into this. |

Rewritten Is2EdgeTransitive to be much more efficient. Now uses Orbit-Stabiliser Theorem.
