4 paths for adjacent vertices too.
Indeed the number of pairwise vertexindependent paths for any pair of nonidentical vertices from any Platonic polyhedron is equal to the number of edges meeting at each vertex (so 3 for a tetrahedron, cube or dodecahedron, 4 for an octahedron and 5 for an icosahedron).
