On chief factors of parabolic maximal subgroups of the group ${}^2F_4(2^{2n+1})$
This article continues  the previous papers of the author where it is obtained a refined description of the chief factors of a parabolic maximal subgroup that involve in its unipotent radical for all finite simple groups of Lie type (normal and twisted) besides for the groups  ${}^2F_4(2^{2n+1})$ and $B_l(2^n)$. In present paper,  such description for ${}^2F_4(2^{2n+1})$ is given. It is proved a theorem, in which, for every parabolic maximal subgroup of the group ${}^2F_4(2^{2n+1})$, a fragment of its chief series that involves in the unipotent radical of this parabolic subgroup is given. Generating elements of the corresponding chief factors are presented in a table.
