• Expansion of log(1+log(1+sinh(x))).at n=7A009309
• a(n) = (n+1)*(a(n-1)/n + a(n-2)), with a(0)=1, a(1)=2.at n=9A013989
• 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=9A053018
