• Triangle read by rows: T(m,k) = normalized partial derivative of (t,z) -> exp(t*g(z)) at (0,0), where 2*g(z) = 1 + exp(-2*z*g(z)).at n=23A078751
• Exponential Riordan array (1,4*x+6*x^2+4*x^3+x^4).at n=30A187084
• Triangle read by rows. T(n, k) are the coefficients of polynomials p_n(x) based on the Eulerian numbers of second order representing the Bernoulli numbers as B_n = p_n(1) / (2*(2*n - 1)!).at n=17A356547
