Task: Question Answering
Input (English): Passage: Rotational symmetry -- For symmetry with respect to rotations about a point we can take that point as origin. These rotations form the special orthogonal group SO(m), the group of m×m orthogonal matrices with determinant 1. For m = 3 this is the rotation group SO(3).
Question: is point symmetry a special type of rotational symmetry
