I believe it to be the 10 minute block. It would be a bear to add a small square in the middle of triangles. It looks like the middle square is cut smaller than the squares made of 1/2 sq. triangles.
Doesn't matter if they are whole squares or squares made up of 1/2 Sq. triangles. A square is a square.
