Therefore the ,centralizer, and hence also the ,normalizer, of a ,subgroup, of order r in each of the above groups is soluble. For the group L2(q) with q = pm we let r = p. Then the ,normalizer, of a ,subgroup, of order p in L is also soluble. This concludes the classical case. If L is an exceptional group then we define a special prime r = r(L) as ...

Electro-hydraulic power steering, is an extension of the well-known hydraulic power, steering,. The main difference is how the hydraulic pump that supplies the pressure necessary for the power steering is driven. In, electro-hydraulic power steering,, an electric motor drives the pump, which is controlled according to the required assisting steering force.

Let G be an F C-group, and let X be an almost ,normal subgroup, of G. Then X is nearly ,normal, in G. Proof: As the ,normalizer, NG(X) has finite index in G, there exists a finitely generated ,subgroup, of G Esuch that G = hE, NG(X)i. Moreover, the ,subgroup, Ecan be chosen ,normal, in , since its ,normal, closure G EG is like-wise finitely generated.
