1. Rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation. Therefore a symmetry group of rotational symmetry is a subgroup of E+(m) (see Euclidean group). An object or figure which is indistinguishable from its transformed image is called mirror symmetric

3. in my pattern the shape starts with one square then 2 squares then 3 squares then 4 squares.
