数字拒绝不道歉
Digit Reversal Without Apology
摘要:
1966年,Alan Sutcliffe发表了一篇介绍性的论文,题目是“当数字颠倒时相乘的数字”。两年后,T。J. Kaczynski扩展了Sutcliffe的工作,证明了存在一个3位数的基数n具有此属性,当且仅当存在一个2位数的基数n具有此属性。本文试图将Kaczynski的证明推广到4位和5位整数的情况,并探讨了这种推广的一些意想不到的后果。
英文摘要:
In 1966, Alan Sutcliffe published an introductory paper on "numbers which are multiplied when their digits are reversed". Two years later T. J. Kaczynski extended Sutcliffe's work to show that there exists a 3 digit number in base n with this property if and only if there exists a 2 digit base n number with this property. This paper attempts to generalize Kaczynski's proof to the case of 4 and 5 digit integers and explores some unexpected consequences of this generalization.
