The number of solutions for each order is always an even number because each basic solution has a complement, which, after normalizing, is also a basic solution. Another way to say this is that all basic solutions come in pairs that are complements of each other. All other orders do have such solutions, including order-12, thus ending speculation that this is a feature of even orders. Order-5 has been included in this study for comparison purposes although it is not a pure magic star. With this one exception this study is limited to pure magic stars only.
Lists are of basic solutions only.
Each order has 2n-1 disguised versions. So order-14 with over 7 million basic solutions has over 196 million apparently different solutions. Because of the large file sizes for order-9 and higher, I include condensed lists only, showing some solutions at the start and end, and when the value of cell a changes.
