The diagram below depicts a geometric configuration consisting of 16 nodes and 12 lines. Notice that each node is on exactly three lines and each line contains exactly four nodes. The fact that 3x16 = 4x12 = 48 characterizes what mathematicians would call a nonsymmetric configuration or block design of size (16,12). This one is named BRUNES' STAR.
