• a(n) = 3*(n+1)*binomial(n+2,6).at n=15A027779
• Group the even numbers as 2, (4,6), (8,10,12), (14,16,18,20), (22,24,26,28,30), ... then a(n) = LCM of the n-th group.at n=5A062080
• Triangular array T(n,k) read by antidiagonals: T(2,1) = 1; otherwise T(n,k) = p(n)!/(p(k)!*p(n-k)!), where p(0)=1 and p(m)=prime(m) for m > 0.at n=38A360207
