Is the linear algebra p 1p2p3 a natural number ordering?
Yes Linear algebra is a branch of mathematics, and its research objects are vectors, vector spaces (or linear spaces), linear transformations and linear equations with finite dimensions. Let n elements be n natural numbers from 1 to n, and specify the standard order from small to large. Let p1p2p3 ... pn ... pn be the arrangement of these n natural numbers, and consider the element Pi (I = 1, 2, ..., n). If there is a ti element greater than π and before π, it is called the reverse order of π.
