1 quaternionic projective line
The quaternionic projective line or extended quaternionic line is a shape homeomorphic to a tetrasphere that is constructed from taking the projective line over the ring of quaternions. The quaternionic projective consists of the quaternionic line and a point at infinity ∞.
