| ## Description
 | ||
| <section id="description">考虑到包含重复数字的4位数素数,很明显它们不能全部相同:1111可被11整除,2222可被22整除,依此类推。但是有九个4位数的素数包含三个素数:1117,1151,1171,1181,1511,1811,2111,4111,8111我们将说M(n,d)表示n-的最大重复数位数。数字素数,其中d是重复数字,N(n,d)表示这些素数的数量,S(n,d)表示这些素数的总和。所以M(4,1)= 3是4位数的素数的最大重复位数,其中一个是重复的数字,有N(4,1)= 9个这样的素数,这些素数的总和是S (4,1)= 22275.事实证明,对于d = 0,只能使M(4,0)= 2个重复数字,但是存在N(4,0)= 13个这样的情况。同样地,我们获得了4位素数的以下结果。 <p>数字,d M(4,d)N(4,d)S(4,d)0 2 13 67061 1 3 9 22275 2 3 1 2221 3 3 12 46214 4 3 2 8888 5 3 1 5557 6 3 1 6661 7 3 9 57863 8 3 1 8887 9 3 7 48073 </p><p>对于d = 0到9,所有S(4,d)的总和是273700.求所有S(10,d)的总和。 </p></section>
