[Gmsh] hexagonal surface tiling

[Mark Smith]

Hi,You might like to look at Thomson Problem - Points on a Sphere there is the ability to export the nodal positions of the triangles that form the surface which can be converted to gmsh format quite easily,

Hi All, 
Would anyone know if it’s possible to generate a hexagonal / pentagonal surface tessellation of a sphere? 
I’d like to be able to generate a sphere, tesselate the surface in hexagons/pentagons, then extrude the surface out in the normal direction to create a mesh of high order prisms. 
Something similar to the attached figure. 
If it’s only possible to tile the surface with quads, how would I go about extruding the 2D surface in the normal direction. 
Thanks
