Abstract. Hanging modified theta graphs are obtained from attaching a modified theta graph to each teeth of comb graph P
L
, where P
denotes a path on a
vertices. In this paper it is proved that symmetric hanging modified theta graphs and non-decreasing symmetric hanging modified theta graphs are graceful.
