• Let Do(n)=A006566(n)=n-th dodecahedral number. Consider all integer triples (i,j,k), j >= k>0, with Do(i)=Do(j)+Do(k), ordered by increasing i; sequence gives j values.at n=12A053018
• a(n) = n*(n^2 - 1)/2 - 1.at n=40A117560
• Decimal representation of the x-axis, from the origin to the right edge, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 609", based on the 5-celled von Neumann neighborhood.at n=24A283286
