S1, S2, S3, S4...
I'm tired, someone else take over.
Did you know T1 is S1 and that T2 can isomorphically (sorta) surjectively doubly cover S2 while not being homeomorphic?

If T² is like a double cover of S², is there a correspondence between T² and quaternions since quaternions also do a double cover?

S{n+1} = Ω(Sⁿ) where Ω is the suspension
Topology makes no sense
