    33This is nice in principle since `SymmetricGroupAlgebra` makes use of the specific properties of the symmetric group to provide more features (better implementation of the center, Yucis-Murphy elements, ...). However `SymmetricGroupAlgebra` is not a drop-in replacement for the plain group algebra of the symmetric group. In particular it breaks several assumptions of `.algebra` like the fact that the basis of `G.algebra(K)` is indexed by elements of `G` (here the basis is indexed by plain `Permutation`'s); it is therefore likely to create bugs and confusion.

    5 This ticket reverts `SymmetricGroup.algebra` to the default behavior. See #... for a proper plan to endow it with the additional structure of `SymmetricGroupAlgebra`.
