Problem 60982. Mesh the square with triangles

Problem statement
An square is a regular polygon with 4 vertices and 4 edges.
A triangulated mesh T (stands for triangles here) -or a triangulation- is simply a N x 3 matrix of positive integers where each row contains the vertex indices of a triangle, and where N is the number of triangles.
Your task here is to mesh, that is to say give one triangulation T of, this square.To do so, you will list the triangles/rows in a matrix of triangles, T.The row order of the triangles in the list doesn't matter.
Example
The first triangle here can be [1, 2, 3] if counterclockwise oriented.
