A robot moves across a linear track, increasing its position by $(k+1)^2 - k^2$ units in step $k$, for $k = 0$ to $78$. The total distance it travels is the sum of these increments. Meanwhile, a sensor network can register signals at frequencies $t = 3a + 7b + 18$, where $a$ ranges from $1$ to $1213$ and $b$ from $1$ t...

A music producer samples beats at intervals divisible by $99$ within the first $198$ milliseconds and sums their timestamps to get $M$. She then identifies the latest millisecond $P \le M$ that is a prime number. A sound engineer tunes a parameter $(a, b)$, where $a$ ranges from $1$ to $293$ and $b$ from $1$ to $P$, mi...
