• a(n)=(2n)!*(sum{k=1...2n}1/k)/(2n+1).at n=5A114450
• Square array read by antidiagonals: T(m,n) = H(n,2*m)*(2*m)!/(2*m+2*n-1). H(0,m) = 1/m, for all positive integers m. H(n,m) = Sum_{k=1..m} H(n-1,k).at n=19A136205
• a(n) is the first term k of A329902 for which A056239(k) = n.at n=35A330743
• Primorial deflation of A133411(n), where A133411(n) is the smallest highly composite number of the form k*a(n-1) where k is an integer greater than 1.at n=35A330744
