Another large Truncated Tetrahedron

Chuang Chern made another large truncated tetrahedron as shown below.

This one has the horizontal armchair pattern if we define the horizontal direction as shown on the left of the figure , in contrast with the previous large truncated tetrahedron that has zigzag pattern horizontally.

Incidentally, we also have armchair pattern along any direction that connects two pentagons in the current model.
