<![CDATA[Group theory is a field of abstract algebra that studies the structure of sets. Some concepts that are developments of group theory are fuzzy subgroups. Suppose that G is a group, a fuzzy subset μ of G is called a fuzzy subgroup of G if it satisfies and for each . However, not all groups have fuzzy subgroups. The aim of this research is to show that is a classical group with multiplication operations in the group and determine fuzzy subgroups in the group . From the research results, it is found that the subset with prime modulo integers and is a classical group with group multiplication operations and the fuzzy subset in the group is a fuzzy subgroup and in general The properties of the classical group apply to the fuzzy subgroup, namely the singularity of the identity and the singularity of the inverse. However, there are properties of classical groups that do not apply to fuzzy subgroups, namely the law of cancellation]]>
