| ## Description
 | ||
| <section id="description">对于一些正整数k,存在形式为4t = 2t + k的整数分区,其中4t,2t和k都是正整数而t是实数。 <p>前两个这样的分区是41 = 21 + 2和41.5849625 ...... = 21.5849625 ... + 6。 </p><p> t也是整数的分区称为完美。对于任何m≥1,让P(m)为k≤m的完美分区的比例。因此P(6)= 1/2。 </p><p>在下表中列出了一些P(m)P(5)= 1/1 P(10)= 1/2 P(15)= 2/3 P(20)= 1/2 P(25)= 1/2 P(30)= 2/5 ... P(180)= 1/4 P(185)= 3/13 </p><p>找到P(m)<1/12345的最小m </p></section>
