Find a group G that contains elements a and b such that a 2 = e, b 2 = e, but the order of the element a b is infinite. My attempt: Clearly G cannot be abelian. So I looked at two commonly known non-abelian groups, namely. (i) The group of symmetries of the equilateral triangle. (ii) 2 by 2 matrices. Neither of these seem to work.
