Abstract
The concept of canonical decomposition of an arbitrary subalgebra of the algebraAO(1,n) is introduced. With the help of this decomposition all maximal subalgebras L of rankn−1 of the algebraAP(1,n), satisfying the conditionL ∩V=<P1,...;P n>, whereV=<P 0,P 1,...,P 1> is the space of translation are described.
