Transformations (e.g. rotations) in n-dimensional spaces. Higgins (?)
originally proposed quaternions (sp?) to address the 3 space problem,
but they're ugly and don't generalize.
"Ugly" is a matter of opinion, but the use of quaternions in
describing
rotations does generalize to n dimensions via Clifford algebras
and spin groups.
