👉 The term "straitest" is typically used in the context of mathematics to describe a linear transformation that preserves distances between points. Specifically, it can be defined as a continuous mapping \(T : \mathbb{R}^n \to \mathbb{R}^m\) such that for every two distinct points \(x_1, x_2 \in \mathbb{R}^n\) and \(y_1, y_2 \in \mathbb{
