【 摘 要 】

This paper presents someresults on the simple exceptional Jordan algebra over an algebraicallyclosed field $Phi$ of characteristic not $2$. Namely an example ofsimple decomposition of $H(O_3)$ into the sum of two subalgebrasof the type $H(Q_3)$ is produced, and it is shown that thisdecomposition is the only one possible in terms of simplesubalgebras.
