Abstract: In this paper, we give concept of intuitionistic fuzzy point (IFP), and give two kinds of definitions of intuitionistic fuzzy subgroups (IFSG) by the use of t-norm and s-norm, and discuss their properties, we also introduce normal IFSG of a group G, and build intuitionistic fuzzy quotient qroup of a group.
