If we add one more Square pyramid on the Metabiaugmented hexagonal prism ,then we can get the Triaugmented Hexagonal prism ;which is also a combination of hexagonal prism and Square pyramids.It has one hexagonal prism and three Square pyramids.

   We can observe that there is one square between any two Square pyramids ;if we want to construct the Triaugmented Hexagonal prism ,then we can construct Augmented  hexagonal prism first ,and construct another Square pyramid such that the three Square pyramids are mutually not adjacent.It is known as the Jhonson solid .
