http://www.map.mpim-bonn.mpg.de/2-manifoldsWebIn mathematics, a solid torus is the topological space formed by sweeping a disk around a circle. [1] It is homeomorphic to the Cartesian product of the disk and the circle, [2] endowed with the product topology . A standard way to visualize a solid torus is as a toroid, embedded in 3-space.

We have $\alpha$ is in a different homology class from $\beta$, and so we’ve found that there are $3$ homology classes (including the class of boundaries). This is a big problem, because $3$ is NOT a power of $2$: It isn’t $2$, and it isn’t $4$ either!
