## Description
<section id="description">可以证明对于每个整数n多项式n4 + 4n3 + 2n2 + 5n是6的倍数。还可以显示6是满足该属性的最大整数。 <p>将Mabc定义为最大m使得n4 + an3 + bn2 + cn是所有整数n的m的倍数。例如M4,2,5= 6。 </p><p>此外将SN定义为所有0 &lt;abc≤N的Mabc之和。 </p><p>我们可以验证S10= 1972和S10000= 2024258331114。 </p><p>设Fk为斐波纳契数列对于k≥2F0 = 0F1 = 1且Fk = Fk-1 + Fk-2。 </p><p>求最高9位数为ΣSFk为2≤k≤1234567890123。 </p></section>
