• Theta series of 14-dimensional integral laminated lattice LAMBDA14.4 with minimal norm 4.at n=5A047627
• Start with a square; at each stage add a square at each expandable vertex so that the ratio of the side of the squares at stage n+1 and at stage n is the golden ratio phi=0.618...; a(n) is the number of squares in a portion of the n-th stage (see below).at n=14A269965
