 OFFSET 0,3 LINKS Alois P. Heinz, Rows n = 0..9, flattened EXAMPLE The third set partition is {1,2}, 21 in base factorial is 5, so a(3) = 5. Triangle begins: 0; 1; 3, 5; 9, 15, 11, 17, 23; 33, 57, 39, 63, 87, 35, 59, 83, 41, 65, 89, 47, 71, 95, 119; MAPLE b:= proc(n, m, t) option remember; `if`(n=0, [0], [seq(map( x-> x+j*t!, b(n-1, max(m, j), t+1))[], j=1..m+1)]) end: T:= n-> b(n, 0, 1)[]: seq(T(n), n=0..5); # Alois P.
