### Abstract

In a former paper we studied transformations on the set of all n-dimensional subspaces of a Hilbert space H which preserve the principal angles. In the case when dim H ≠ 2n, we could determine the general form of all such maps. The aim of this paper is to complete our result by considering the problem in the remaining case dim H = 2n.
