The cyclic edge connectivity @l"c(G) of a graph G is the minimum number of edges whose removal results in a disconnected graph and every connected component contains cycles. If @l"c(G) exists, we call G@l"c-connected. And if @l"c(G) gets the maximum value, we call G@l"c-optimal. A bipartite graph is said to be half vertex transitive if its automorphism group is transitive on the sets of its bipartition. In this paper, we show that a connected k(=4)-regular half vertex transitive graph G with girth g=6 is @l"c-optimal, and we also obtain a sufficient and necessary condition for a connected k(=4)-regular half vertex transitive graph G with girth 4 to be @l"c-optimal.
