Each block is composed of four identical spheres. Configurations of the five blocks are different from each other. The five blocks are combinable with each other to form a detachable stacked arrangement shaped as a regular triangular pyramid. The stand is formed with ten concaves for accommodating a portion of a bottom layer of the stacked arrangement. The five blocks are stackable on the stand to form the stacked arrangement by at least four different sequences."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Densely stackable building block system","description":"A densely stackable building block system comprises a stand and exactly five three-dimensional blocks.
