자연수의 분할(partition)과 rank/crank 목록

 

 

개요

• 분할의 rank = 분할에서 가장 큰 수 - 분할의 크기
• 예
  
  • 9의 분할인 {7,1,1}의 경우, rank=7-3=4
  • 9의 분할인 {4,3,1,1}의 경우, rank=4-4=0
• 분할수에 대해서는 200까지의 분할수 목록

재미있는 사실

• In 1944, the crank was first hinted at by Freeman Dyson (2), then an undergraduate at Cambridge University. He had written an article, titled Some Guesses in the Theory of Partitions, for Eureka, the undergraduate mathematics journal of Cambridge.
