there is no sphere built only by hexagons?
That's right...the closest would be the pentagon (12 pentagons should end up in a closed body...not really a sphere).

I guess that's true, but once you've got a 12 pentagon 'sphere' it won't be hard to smoothen the result. 
As for the formula, it should be somewhere on the internet for sure, I'll do some searching later today if I don't forget,
Cheers

why do you need this?
i just thought about having a ball out of such objects (hexagon or pentagon doesnt really matter for me) would look cool and allow some fun

you could download the source code of programs like blender or wings3d and look where the icosphere primitives get generated in the code.
i guess i wouldnt even find the lines where this happens

It's this function in the Blender source-code, but I couldn't find it: Code:
IcoSphere(float, int, Appearance)
