Thanks! So my final question on this topic is how do I only count sites (cells) that are orthogonal in the same layer and only face adjacent (U, D) between layers?

Would counting adjacent sites (cells) that share 4 edges work? When the board is defined as (board (layers 3 (square 3))), do all sites (cells) get associated with 8 vertices instead of 4?

Alternatively, I could define the Qua 3D game board as playing on vertices, and use single edges as the Orthogonal directions. Please confirm that the Ludii player does not consider vertices that are in diagonal directions across a square as Orthogonal. Also, how would I define the Qua game board as playing on vertices as sites instead of cells?
