The sphericity of a graph G is the smallest integer n such that G can be represented as the intersection graph of a family of unit-diameter spheres in Euclidean n-space E n. We determine here the sphericities of the graph of semiregular polyhedra in E 3 except a few prisms.
The number of words of weight w in the product code of linear codes with minimum distances d, and d, is expressed in the number of low weight words of the constituent codes, provided that w <d,d, + max(d,, d<). By examples it is shown that, in general, the full weight enumerator of a product code is
