Yes, why should it do so? Every finite dimensional operator can be
represented by a matrix.

The generalised transposition should be able to arbitrarily permute the
dimensions of a tensor. A generalised multiplication may fuse the last
dimension of the first tensor with the first dimension with the second
tensor. E.g. dimensions [a,b,c,d] and [d,e,f,g] result in [a,b,c,e,f,g].
