For every affine algebraic group G over an algebraically closed field, every finite abelian subgroup A with |A| not divisible by the characteristic lies in some maximal torus up to index dividing the Grothendieck torsion index t(G).
As we pointed out in the Introduction, we have (4.1) /u1D4613(/u1D43A)| /u1D4612(/u1D43A)| /u1D461(/u1D43A)

Finite abelian subgroups of algebraic groups
For every affine algebraic group G over an algebraically closed field, every finite abelian subgroup A with |A| not divisible by the characteristic lies in some maximal torus up to index dividing the Grothendieck torsion index t(G).
