Let $C$ be the number of ordered pairs $(i,j)$ of integers with $1 \leq i \leq 62$ and $1 \leq j \leq 140$ such that $\gcd(i,j) = 1$. Compute the remainder when $C \cdot F_n$ is divided...

alg_sym_quad_system_v1_1218484723_6733
An engineer analyzes vibration modes in a triangular framework. Each mode is described by positive integers $(a, b, c)$ representing three stiffness parameters, which must satisfy $$a^{2} + b^{2} + c^{2} = ab + bc + ca$$ and $$9a + 8b + 4c = K,$$ where $K$ is the number of distinct loads $t$ that can be produced in the...

Let $n$ be the number of ordered pairs $(i, j)$ of positive integers such that $1 \leq i \leq 7$, $1 \leq j \leq 8$, and $i + j = 9$. Compute $6! \cdot S(n, 6)$, where $S(n, 6)$ is the Stirling number of the second kind.
