• Consider primitive solutions (x,y,z) to x^4+y^4+z^4=w^4 with 0<x<=y<=z arranged in order of increasing w; sequence gives x values.at n=0A078518
• Large-number statistic from the enumeration of domino tilings of a 9-pillow of order n.at n=18A112843
• Numbers k such that k^4 = x^4 - y^4 - z^4.at n=0A175598
• Number of length 4 0..n arrays with each partial sum starting from the beginning no more than two standard deviations from its mean.at n=16A244835
• Larger of amicable pair m < n defined by t(n) = m and t(m) = n where t(n) = psi(n) - n and psi(n) = A001615(n) is the Dedekind psi function.at n=30A323330
• Expansion of 1/(2 - g^2)^2, where g = 1+x*g^2 is the g.f. of A000108.at n=7A390423
