%N Triangle read by rows in which row n contains the smallest nontrivial set of n consecutive numbers divisible by the next n numbers respectively. The next n numbers are numbers from n(n1)/2 +1 up to n(n+1)/2.
%C The first term of the nth row is LCM of the next n numbers + first among them. r the nth row contains n consecutive numbers beginning with LCM of {(n(n1)/2 +1),(n(n1)/2 +2),... up to (n(n+1)/2)} + n(n1)/2 +1.
