I am confused. Then don't you need a ses of etale sheaves on $Spec(\mathbb{Z})$ ? The exact sequence we have is only an exact sequence on $Spec(\mathbb{Q})$.

How to compute class number of a torus

are you using etale cohomology or Galois cohomology here ?

Thank you for your answer. Could you please elaborate a bit more about the exact sequence relates the class numbers and the unit groups ?

Thank you very much for your answer. Does that mean, there is no integral basis for $Lie(A)$ in the general case then ?
