  We look into the general aspects of space-time symmetries in presence of
torsion, and how the latter is affected by such symmetries. Focusing in
particular to space-times which either exhibit maximal symmetry on their own,
or could be decomposed to maximally symmetric subspaces, we work out the
constraints on torsion in two different theoretical schemes. We show that at
least for a completely antisymmetric torsion tensor (for e.g. the one motivated
from string theory), an equivalence is set between these two schemes, as the
non-vanishing independent torsion tensor components turn out to be the same.
