In this paper we shall study the upper fuzzy index with the upper fuzzy
subgroups, also we shall give some new definitions for this subject. On the other
hand we shall give the definition of the upper normal fuzzy subgroups, and
study the main theorem for this. We shall also give new results on this subject.
