Let $S$ be the set of all nonnegative integers $j$ such that $0 \leq j \leq 83$ and $\binom{83}{j}$ is odd. Let $u$ be the sum of all elements in $S$. Determine the number of positive integers $n$ such that $n \leq u$ and $16$ divides the $n$th Fibonacci number. Let $r$ be this count. Compute the remainder when $44121 ...
