Abstract
This is the final part of the paper on the dimensions of Jordan blocks in the images of regular unipotent elements from subsystem subgroups of type (C_2 ) in (p)-restricted irreducible representations of groups of type (C_n) in characteristic (pgeq 11 ) with locally small highest weights. Here the case where (n>3 ) and the restriction of a representation considered to a canonical subgroup of type (A_1) containing such element has a weight not less than (p), is investigated.

Abstract
We find conditions such that every (lambda )-homogeneous model with small ( lambda ) satisfying these conditions is homogeneous. As a corollary, we obtain conditions guaranteeing that the following implication holds: If (T ) is a theory, (mu >|T| ), and every model of (T ) of cardinality ( mu ) is (omega _1)
