In this paper, we use the known classification of the finite capacity
simple alternative pairs and the version of the Litoff Theorem far Jor
dan pairs to describe all the strongly prime alternative pairs with no
nzero socle. We study the inheritance of some properties (primeness, n
ondegenerancy,...) when passing from the original alternative pair to
the symmetrized pair. Thus, we can apply Jordan theoretical results to
the alternative case.
