Query: Block representations of generalized inverses of matrices   In this paper will be considered standard forms of generalized inverses for
matrices in the shape of block representations {1, 2, 3, 4, 5, 5^k}-inverse.
Especially will be considered Moore-Penrose inverse and the group inverse.
Results from Rhode's technique are used and methods for calculating some
inverse are shown on examples.
