• Triangle whose (i,j)-th entry is binomial(i,j)*11^(i-j)*12^j.at n=18A038326
• Triangle whose (i,j)-th entry is binomial(i,j)*12^(i-j)*11^j.at n=17A038337
• a(n) = n * (n+1)^2 * (n+2)^3.at n=10A101213
• Let df(n,k) = Product_{i=0..k-1} (n-i) be the descending factorial and let P(m,n) = df(n-1,m-1)^2*(2*n-m)/((m-1)!*m!). Sequence gives P(6,n).at n=12A132464
• a(n) = Product_{k=0..n} (n^2+k)^k.at n=2A272237
