The Great Square (TGS) is what is called the absolute everything, because voids, without anything, get erased in seconds. The Great Square contains The Great Triangles, which are stacked upon each other. Just like The Great Triangle, The Great Square's rim is made out of Adadai-1, the inside is made out of Adadai- and when viewed from any direction, it will always apear to face the viewer. When stepped inside, like a portal, it engulfs the view of the person.
The Great Square is the last in the sequence of Mandelbrotverses.
While The Great Square is made inside out of the same substance as The Great Triangle, they are of differing colors, because the way the Triangles are packed is different of that from the fractal patterns inside of the Triangles. Also, their rims add to the overall brightness of the colors.
