| May 15, 2021 at 16:41 | comment | added | WhatsUp | I'm not convinced by the argument in your last paragraph. For example, if we ask instead the number of parity under the whole board, then we can still write it as $R_{1, *} + R_{2, *} + \dots + R_{8, *}$. These $8$ vectors (or matrices, in your language) are also linearly independent, thus the last paragraph of your argument seems to imply that the answer for this variation is also $8$. This however is obviously wrong, as the whole board is just one single rectangle. | |
