Drag the red point to form a single row of numbers. Similarly, we make a 4 x 5, a 5 x 4, and a 10 x 2 array. If the number of rows and columns in the array are equal and prime, the array will contain exactly three numbers shaded blue. If the array has at least 2 columns and 2 rows, then the number it represents isn't prime. Poetic Forms: 1, 2, 4, 7, 8, 9. Clearly x 2 + n ⁢ y 2 superscript x 2 n superscript y 2 x^{2}+ny^{2} is a reduced form of discriminant - 4 ⁢ n 4 n -4n . We found a way to create arrays with exactly four numbers shaded blue. After so many months of evaluating slidable, twistable, bendable and detachable machines, we'd (hopefully) be forgiven for believing we'd seen every possible form factor. For n ∉ { 1 , 2 , 3 , 4 , 7 } n 1 2 3 4 7 n\notin\{1,2,3,4,7\} , we will produce a second reduced form of the same We now consider the prime power case, taking 2 r superscript 2 r 2^{r} and p r superscript p r p^{r} , p p p an odd prime, separately.
