alg_sym_quad_system_v1_1218484723_3037
A logistics company assigns three types of containers—A, B, and C—to shipments. Each container type has a volume equal to its label number cubed. The total squared volume satisfies $a^2 + b^2 + c^2 = ab + bc + ca$, and the weighted load $4a + 5b + 9c$ must match the number of distinct shipment weights possible using co...

A score is computed using the formula $-1088ab^3 + \left(\sum x\right)a^2b^2 - 1088a^3b + 272a^4 + 272b^4$, where the sum is over roots $x$ of $x^2 - 1632x - 164065 = 0$.
