## Description
<section id="description"> nradn的基数是n的不同素因子的乘积。例如504 = 23×32×7因此rad504= 2×3×7 = 42.如果我们计算1≤n≤10的radn则在radn上对它们进行排序并进行排序如果激进值相等我们得到未分类<p>排序n radn </p><p> n radnk 11 </p><p> 111 22 </p><p> 222 33 </p><p> 423 42 </p><p> 824 55 </p><p> 335 66 </p><p> 936 77 </p><p> 557 82 </p><p> 668 93 </p><p> 779 1010 </p><p> 101010令Ek为有序n列中的第k个元素;例如E4= 8且E6= 9.如果radn按1≤n≤100000排序则找到E10000</p></section>
