editThere's an error in one of the binomial coefficients listed for 7140:
{7140 \choose 1} = {239 \choose 2} = {36 \choose 3}
239 is an error because 239*238/2 = 28441, not 7140.
The correct value for this binomial coefficient is
{120 \choose 2}
120*119/2 = 7140.

editIn 1995, 3003 was the only known number appearing 8 times [1]. Is this still the case? DRLB (talk) 22:17, 29 January 2008 (UTC)
- Perhaps David Singmaster knows the answer to that one; you could ask him. Michael Hardy (talk) 23:00, 29 January 2008 (UTC)

First appearance of the term?
editI conjecture that Rodica Simion's Ph.D. thesis in 1981 was the first occurrence in print of the term that is the title of this article. I find it in a 1989 paper written by others, but there it refers to something else—a conjecture on permutations. Michael Hardy (talk) 12:34, 14 May 2009 (UTC)
