👉 "Unsketchable" is a term used in mathematics and computer science to describe a mathematical object that cannot be represented or described precisely using only finite, logical operations. In other words, it represents an abstract concept or pattern that can't be easily expressed or visualized with the tools of modern algebra. For example, the set of all natural numbers (N) is unsketchable in the sense that there's no way to describe it exactly without referring to a larger collection of objects.
