BEST theorem provides a polynomial-time algorithm for enumeration of Eulerian circuits in a given directed graph. Is there is a readily available implementation of it in Sage?
Apparently, BEST formula can be implemented as
def BEST_count(G):
return G.spanning_trees_count() * prod(factorial(G.in_degree(v)-1) for v in G.vertices())
