If ris also irreducible in Z_nand f~n~κ≡fmodn,r(xfor all f∈Z_nthen we call n a Carmichael number of orderκmodulo r.Denote the set of all such numbers by C_κ,r(x.Define C_κ=∪_r(xC_κ,r(x,where rpasses through all monic irreducible polynomials over Z of degreeκ.We call elements of the set C_κCarmichael numbers of orderκ.ZHU and SUN[Journal of Sichuan University,42;1(2005), 47-51]first gave a necessary condition for Carmichael numbers of order 3.Then they gave a sufficient condition for Carmichael numbers of order 3,but did not find any such numbers less than 10~8 satisfying the sufficient condition.At last,they asked three questions;1.is the necessary condition also sufficient?

f∈Z_n，就称n是模r的κ阶Carmichael数，用C_κ，r(x表示所有这种数的集合，定义C_κ=∪_r(xC_κ，r(x，这里r跑遍Z中所有κ次首一不可约多项式，C_κ里面的元素就称为κ阶Carmichael数，C_κ称为κ阶Carmichael数集，朱文余和孙琦[四川大学学报，42；1(2005)，47-51]首先给出了3阶Carmichael数的一个必要条件；然后又给出了这种数的一个充分条件，并发现10~8内没有满足此充分条件的这种数；最后他们提出三个问题；一、问必要条件是否也是充分的？

Memorize numbers module — In this task, subjects must recall numbers that are given at baseline, then carry out an arithmetic "distractor" task, then reproduce the numbers given at the outset."If you have 2 numbers, it's easy, but if you have 10 numbers and then a distractor task, your working memory is working very hard to get this information," Dr. Penner notes.

记数模组—在这个任务中，受试者必须记住一开始给予的数字，之后进行算数诱答任务，接著再现一开始给予的数目；Penner博士指出，如果你有两个数字，那是简单的，但是如果有10个数字，然后进行诱答任务，你的操作记忆会难以得到此资讯。
