abstract = {Summary: The 3-dimensional sphere can be thought of as a union of two solid tori glued along their boundaries. Those come from torus-fibrations, and this short note explores some elementary facts of how $\text{SO}(4)$ operates on them with connections to Hopf fibrations and quaternionic multiplication.},
