> This rectangular world map called AuthaGraph World Map is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining areas proportions and unfolding it to be a rectangle.
> The world map can be tiled in any directions without visible seams. From this map-tiling, a new world map with triangular, rectangular or parallelogram’s outline can be framed out with various regions at its center.

> It shows there are no "four corners of the earth" by arranging several world maps without visible seams around a world map with color. You can see Antarctica at the right bottom is close to not only South America but also Africa and Australia.
