摘    要:朱文余和孙琦(见《数学进展》,2004,33(4):505-507)提出了关于3阶Carmichael数的三个问题,我们(见《四川大学学报(自然科学版)》,2006,43(6):1197-1201)肯定地回答了问题1.本文模仿Howe的寻找严格2阶Carmichael数(见Mathematics of Computation,2000,69(232):1711—1719)的方法,提出寻找满足某种条件的3阶Carmichael数的方法,并用这种方法确实找到了几百个这样的数,因而完全肯定地回答了问题2.

关 键 词:k阶Carmichael数  严格k阶Carmichael数  不可约多项式

Abstract:ZHU and SUN [Advances in Mathematics, 33:4 (2004), 505-507] posed three questions on Carmichael numbers of order 3. We [Journal of Sichuan University (Natural Science Edition), 43:6 (2006),1197-1201] answered Question 1 affirmatively. In this paper, we answer Question'2 affirmatively by presenting a method for finding examples of Carmichael numbers of order 3 satisfying certain conditions and using the method to provide hundreds of such examples. Our method is an analog to Howe's one for finding rigid Carmichael numbers of order 2 [Mathematics Of Computation, 69:232(2000), 1711-1719].
Keywords:Carmichael numbers of order k  rigid Carmichael numbers of order k  irreducible polynomials over the ring of residues modulo n
