Two-Hundred-Fifty-Six, the sixteen-by-sixteen square! She is a gigantic square bigger than Sixteen! She maybe goofy, but don't call her bad names! She's a super-square! She is also in the geometric sequence... Two-Hundred-Fifty-Six has purple limbs, two array displays, pink eyes, light-red mouth, indigo pants and a octagon badge with a number, "256".
