A universal set is a set which contains all the elements or objects of other sets, including its own elements.

that contains exactly those elements x of A that satisfy A typical universal set in mathematics is the set of natural numbers as shown below: N = {1, 2, 3, 4, ...}. Sets are usually named with a capital letter. ∣ However, universal sets can also be finite sets.

However, this conflicts with Cantor's theorem that the power set of any set (whether infinite or not) always has strictly higher cardinality than the set itself. . Graphical characteristics:Asymmetric, Closed shape, Monochrome, Contains both straight and curved lines, Has no crossing lines.
