Talk:Singmaster's conjecture

[Untitled]
There'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.

3003
In 1995, 3003 was the only known number appearing 8 times. 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?
I 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&mdash;a conjecture on permutations. Michael Hardy (talk) 12:34, 14 May 2009 (UTC)
