You are correct, sir. It is one lattice point for each centered face.
So, for the F centered lattices which have a face centered lattice point
on all faces you add 3 lattice points to the original primitive lattice
point for a total of 4 lattice points.
It's all in "the Tables."
Cheers,
Chris
Thanks for the translation, and a correction of the translator:

points per cell.
Is this so? Ortho F and FCC have 4 Bravais vectors
All (in full translation) in chapter 5 of BMC.

Dear all
I have a confusion on the space group R32 and H32. For a cell parameter of a =
b not equal to c, alpha=beta, not equal to gamma, is it considered as R32 or
H32?
I tried searching the mail list archives but it does not help a beginner
crystallographer like me.
I also have another basi
