A good code has both rate k/n and relative minimum distance d/n
large. The fundamental question of coding theory is to describe the closure
of the set of points (d/n,k/n). Goppa's conjecture says that, except for isolated
points, it's the region below the curve y=1-H(x) for x<1/2, where H is the
binary entropy function. I'll describe this and a tantalizing connection with
hyperelliptic curves that led us briefly to think we'd disproved the conjecture.
