As its application, we have constructed real octonion algebras as well as related octonionic triple system in terms of 8-component spinors associated with the Clifford algebras $C(0,7)$ and $C(4,3)$.30 pages, UR1377High Energy Physics - TheoryRepresentations of Clifford Algebras and its Applicationstext
