Expert Answer Transcribed image text: Any translations can be replaced by two reflections. You can rotate a rectangle through 90 degrees using 2 reflections, but the mirror line for one of them should be diagonal. While one can produce a rotation by two mirrors, not every rotation implies the existence of two mirrors. The term "rigid body" is also used in the context of quantum mechanics, where it refers to a body that cannot be squeezed into a smaller volume without changing its shape.

Any translation can be replaced by two reflections. Enter your email for an invite. Clearly, well measured data to 1.5 resolution contain more information than a data set to 3.5 resolution and are therefore likely to lead to a more correct structure, but nominal resolution in itself just tells us how many reflections were used . Therefore, we have which is . Any translation can be replaced by two rotations. And, at long last, the "answer" to your question: $(k,1)\ast(k',1) = (k-k'\text{ (mod }n),1+1\text{ (mod }2)) = (k-k'\text{ (mod }n),0)$, which is a rotation (because, just like a light switch, two flips cancel each other out).
