This paper presents research work conducted at the Chinese Academy of Sciences, on the Vega Grid technology and dynamic geometry technology, and how the two can integrate to provide a dynamic geometry education system based on grid technology. Such an approach could help solve the interconnect problem, the performance problem and the intellectual property problem for Internet-based education systems.

In ISSAC 2000, P. Lisoněk and R.B. Israel [3] asked whether, for <i>any</i> given positive real constants V,R,A<inf>1</inf>,A<inf>2</inf>,A<inf>3</inf>,A<inf>4</inf>, there are always <i>finitely many</i> tetrahedra, all having these values as their respective volume, circumradius and four face areas. In this paper we present a negative solution to this problem by constructing a family of tetrahedra T<inf>(x,y)</inf> where
