Shouldn't there be a 4-D analogue of A212046 Denominators in the
resistance triangle: T(k,n)=b, where b/c is the resistance distance
R(k,n) for k resistors in an n-dimensional cube.
Nicholas Pippenger, "The hypercube of resistors, asymptotic
expansions, and preferential arrangements", arXiv: 0904.1757v1,
[math.CO], Apr 10, 2009, and also cites a 1914 book by Brooks and
Right now my PC refuses to open arxiv.org, so I can't easily supply
the fractions, nor formula given.
I am referring at the moment to a preview on
