 And similar to the 2-torus, the "n"-torus, T"n" can be described as a quotient of R"n" under integral shifts in any coordinate.That is, the "n"-torus is R"n" modulo the action of the integer lattice Z"n" (with the action being taken as vector addition).Equivalently, the "n"-torus is obtained from the "n"-dimensional hypercube by gluing the opposite faces together.
