• Start with a single triangle; at n-th generation add a triangle at each vertex, allowing triangles to overlap; sequence gives total population of triangles at n-th generation.at n=27A061777
• Inverse binomial transform of A006116, which is the sum of Gaussian binomial coefficients [n,k] for q=2.at n=8A135922
• Erroneous version of: Number of Stanley graphs on n nodes.at n=7A323841
• Coefficients of polynomials related to the sum of Gaussian binomial coefficients for q = 2. Triangle read by rows, T(n,k) for 0 <= k <= n.at n=36A329154
