  A recent paper of A. Sofo proves some results about sums of products of
quadratic alternating harmonic numbers and reciprocal binomial coefficients. In
this paper, we extend his result to cubic alternating harmonic number sums and
develop new closed form representations of sums of cubic alternating harmonic
numbers and reciprocal binomial coefficients. Some inter- esting (known or new)
illustrative special cases as well as immediate consequences of the main
results are also considered.
