Rewrite code with fewer characters

Question

How could I rewrite the following code such that the output (evaluation result) is the same, but is obtained from code having less than 30 characters in total?

Table[Table[{b - a, b}, {b,8}],{a,8}],

I tried for more than an hour, but I can't find the solution to this problem.

Table[{b - a, b}, {a, 8}, {b, 8}] is 26 characters. – bill s Feb 26 '19 at 17:26 — bill s, Feb 26 '19 at 17:26
