A game board has positions labeled from $0$ to $\pi(69911)$, where $\pi(69911)$ counts the primes up to $69911$. On each turn, a player picks integers $a$ and $b$ between $1$ and $14$, and computes the score $41a^2 - 82ab + 41b^2$. A score is valid if it lands on the board. Let $n$ be the number of distinct valid score...

A delivery drone must travel along a rectangular grid path with area exactly $85849$ square units, moving only east and north. The shortest such path has length $S = x + y$, where $x \cdot y = 85849$ and $x, y > 0$. The drone computes the sum of squares from $1$ to $S$, then takes the result modulo $8782$, calling it $...
