DESCRIPTION:Given a graph on n vertices with m edges\, each of
unit resistance\,\n how small can the average re
sistance between pairs of vertices be?\n There ar
e two very plausible extremal constructions -- gra
phs like a\n star\, and graphs which are close to
regular -- with the transition\n between them oc
curring when the average degree is 3. However\, we
\n show that there is a rather surprising constru
ction which is better.\n
