About symmetry operations, point group of Sulfer Dioxide, etc. Need help in this thanks.

(a) Write down all symmetry operations of "Sulfur dioxide". (b) What is the point group of "Sulfur dioxide". (c) What is the transformation matrix of all symmetry operations in the point group of "Sulfur dioxide" based on x, y, z coordinate. (d) What is the transformation matrix of all symmetry operations in the point group of "Sulfur dioxide" based on Rx, Ry, Rz coordinate. (e) Please construct the character table of the point group of "Sulfur dioxide". (f) How many vibration modes is IR active
