• Numbers n such that n divides the (left) concatenation of all numbers <= n written in base 17 (most significant digit on right and removing all least significant zeros before concatenation).at n=9A029534
• Denominators of triangle T(n,k), n>=0, 0<=k<=n, read by rows: T(n,k) is the coefficient of x^(2k+1) in polynomial u_n(x), used to approximate x->sin(Pi*x)/Pi.at n=18A144847
