"semi-regular" should be defined; right now it is not clear what the difference between Johnson and Archimedian solids is. Furthermore, I take it that the platonic solids also count as Archimedian? --Axelboldt
I don't think so. semi-regular, i think has to do with the fact that multiple kinds polygons can meet at a vertex
And platonic solids are definitely not Archimedean. (since there are five platonic solids, and thirteen archimedean ones....)
