Abstract
A densely stackable building block system comprises a stand and exactly five three-dimensional blocks. 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.
