Talk:Frank–Kasper phases

Stoichometries versus unit cells
If I'm not missing something the number of atoms in a unit cell should be a multiple of the sum of the numbers in the stoichometry. But this is not the case in the text for the prototype members of the M, P and R phases. Can anyone elucidate. Lavateraguy (talk) 11:33, 11 August 2017 (UTC)
