Indeed, if A is any

**subset**of the geometry G(&&), we define the rank r(A) of A asthe dimension of the smallest flat which contains A, i.e. as the dimension of the

closure of A. Symbolically, r(A) = D(A) , A c Q(&) . The use of a symbol different

To exploit this fact we consider those

**subsets**of & which are equal to their ownclosures, namely those

**subsets**which satisfy the condition A = A", and call themorthoclosed
