On a conjecture about the autotopism group of the Figueroa's presemifields of order

In [14] was proved that the autotopism group of the Cordero-Figueroa semifield of order is isomorphic to a subgroup of , where . Also a conjecture was proposed for the general case, the autotopism group of a Figueroa's presemifield of order . In this article, under a normality condition, we prove this conjecture
