At the very minimum! Most aquarium makers recommend continuous edge support (or 100% bottom support for plastic tanks.)

Most of the larger aquarium companies that supply the aquatic industry, (Marineland, Perfecto, Aqueon, etc) build stands that only support the 4 corners. At least they all used to.
