A game board consists of squares labeled by positive integers from 1 to 35 in both rows and columns. A square $(a,b)$ is *active* if $41a^2 - 12ab + 20b^2 \le 20961$. Let $M$ be the number of active squares. Players earn points equal to the cube of their turn number over $M$ turns. What is the remainder when the total ...
