But the Caspar-Klug theory imposed its own constraints on the permissible number of protein subunits in a viral capsid. It introduced a parameter, T, called the triangulation number18: if each face of the icosahedron is divided into triangles (triangulated), then T describes their quantity.19 Since each of these triangles, in turn, can be made up of three capsid proteins, and an icosahedron has 20 faces, the total viral capsid protein numbers thus become “quantized” in multiples of 60 (60T).
