comment Custom arrow shaft
Agreed, that's cool. But imagine adding a few vertices, which would requires a lot of fiddling around with Transformations to have the Arrows where they belong. It would be nicer to let Graph do this. But still, very nice idea! +1

@cormullion +1 for the reference. Great page that I also used for many of my implementations.

@J.M. LinearAlgebraMatrixConditionNumber[Table[B[i, m]...` gives 2.63531*10^98 . My comment on the N[#,30] was to remind me that even with N the LinearSolve::luc error occured and that I had to use SetPrecision[#,Infintiy] to get rid of it.
