A designer creates square tiles of size $a \times b$ where $a, b \in \{1,2,\ldots,20\}$, each having a stability score $17a^2 - 16ab + 17b^2$. Scores range from 18 to $M = 7200$, and $V$ is the number of distinct scores in that range. The system requires configurations where $b^4 = 10000$. Given $a$ can go up to 198, h...
