The present paper is the final one in the series of papers [1-6] devoted to a central projection of the projective space $\mathbb P^n$ on its subspace $\mathbb P^k$. In these papers, as well as in the present one, we consider a projection with the following property: the reference points $A_i$ $(i=\overline{1,n+2})$ have images $A'_i$ which are projectively equivalent to so-called model, i.e., an ordered set of generally disposed points $T_i$ in $\mathbb P^k$.
