| Forming PYRAMID with smaller pyramid and octahedron
Please teach me :
Is it possible to form larger Pyramid (triangle-based) with smaller Pyramid and Octahedron ?
For example-
2-level Pyramid:
Octahedron part * 1
Pyramid part (triangle-based) * 4
3-level Pyramid:
Octahedron part * 4
Pyramid part (triangle-based) * 11
If It is possible, how to calculate the numbers of smaller parts of Pyramid and Octahedron
forming a n-level Pyramid with the same method ?
Thank you.
