%N Ordered differences of distinct odd squares, stored in triangle.

%C a(n) = 8*A049777(n). For a guide to related sequences, see A204892.

%C Triangle T(n,k), k>=0, n>=1, read by rows, given by T(n,k) = (2*n+1)^2 - (2*k+1)^2. - _Philippe Deléham_, Mar 07 2013

%e a(1) = s(2)-s(1) = 9-1 = 8,

%e a(2) = s(3)-s(1) = 25-1 = 24,

%e a(3) = s(3)-s(2) = 25-9 = 16,

%e a(4) = s(4)-s(1) = 49-1 = 48,

%e a(5) = s(4)-s(2) = 49-9 = 40.

%e Triangle begins:
