On Chief Factors of Parabolic Maximal Subgroups of the Group 2F4(22n+1)

This study continues the author's previous papers where a refined description of the chief factors of a parabolic maximal subgroup involved in its unipotent radical was obtained for all (normal and twisted) finite simple groups of Lie type except for the groups F-2(4)(2(2n+1)) and B-l(2(n)). In present paper, such a description is given for the group F-2(4)(2(2n+1)). We prove a theorem in which, for every parabolic maximal subgroup of F-2(4)(2(2n+1)), a fragment of the chief series involved in the unipotent radical of this subgroup is given. Generators of the corresponding chief factors are presented in a table.
