“…Subsequently, there are many works devoted to study such topological properties ( [1], [2], [3], [7], [9], [10], [11], [13], [14], [15]). Recently, Taylor et al [17,18] considered the connectedness properties of the Sierpinski relatives with rotations and reflections. Xi and Xiong [19] showed that for a fractal square, it is totally disconnected if and only if the number of cells in the connected components in each iteration is uniformly bounded.…”
