• Number of n-uniform tilings.at n=10A068599
• Number of walks within N^3 (the first octant of Z^3) starting at (0,0,0) and consisting of n steps taken from {(-1, -1, 1), (-1, 0, 0), (1, 0, 0), (1, 1, -1), (1, 1, 0)}.at n=8A150328
• Sequence defined by the recurrence formula a(n+1)=sum(a(p)*a(n-p)+k,p=0..n)+l for n>=1, with here a(0)=1, a(1)=10, k=-1 and l=-1.at n=6A177185
• Number of (w,x,y,z) with all terms in {1,...,n} and 3w>=x+y+z+n.at n=19A212250
• a(n) = a(n-1) + a(n-3) unless a(n-1) and a(n-3) are both even in which case a(n) = (a(n-1) + a(n-3))/2, with a(0) = a(1) = a(2) = 1.at n=36A341312
• a(n) is the number of permutations that avoid 312 and 4321 and whose square avoids 321.at n=14A381859
