- Sequence formed from rows of triangle A046937.at n=39A046938
- Somos's sequence {b(4,n)} defined in comment in A078495: a(0)=a(1)=...=a(10)=1; for n>=11, a(n)=(a(n-1)*a(n-10)+a(n-5)*a(n-6))/a(n-11).at n=28A271949
- G.f.: (1 + x/(1 + x^2/(1 + x^3/(1 + x^4/(1 + ...))))) / (1 - x/(1 - x^2/(1 - x^3/(1 - x^4/(1 - ...))))), a continued fraction.at n=21A285636
- For 1<=x<=n, 1<=y<=n, write gcd(x,y) = u*x+v*y with u,v minimal; a(n) = n^4*s, where s is the population variance of the values of |v|.at n=12A345690
