Note that the quaternions q and −q represent the same rotation. I have also finally finished getting through the introductory chapter of Rotations, Quaternions, and Double Groups by Simon L. Rotations, quaternions, and double groups book download. In other words, the group of quaternions is isomorphic to the double cover Spin(3) of the rotation group SO(3). What on earth groups have to do with solving polynomial equations. This is not really a question about QM, its about the mathematics and terminology used to describe rotations in the study of the rotation group.
