| Aug 16, 2017 at 13:18 | comment | added | Gerry Myerson | There's a paper by Gilbreath on the conjecture, but I haven't seen it: Norman Gilbreath, "Processing process: the Gilbreath conjecture", J. Number Theory 131 (2011) pp.2436-2441 DOI 10.1016/j.jnt.2011.06.008 Zbl 1254.11006 | |

minor typos and capitalization of the title (I should have noticed this in my previous edit - sorry for making two suggested edits).

| Aug 19, 2012 at 6:15 | comment | added | Srilakshmi | When i came to know abt. this conjecture, i thought first row p1, p2, p3, p4,....and second row p2-p1, p3-p2, p4-p3,... and third row p3-2p2+p1...and i ended up with pascal's triangle. i.e. To Prove (n-1)C0 p_n - (n-1)C1 p_(n-1) +...+(-1)^(n-1) (n-1)C1 p1 = 1. This might be done by applying a formula for p_n (for eg. paper by willans ). Then i realised that i forgot about the absolute values of the differences. | |

| Aug 5, 2010 at 18:31 | comment | added | Joseph O'Rourke | It seems you didn't state the conjecture: "the first term in each series of differences appears to be 1" according to Wikipedia. That article says, "As of 2009, no valid proof of the conjecture has been published." It has been verified up to $10^{11}$. | |
