"The Brent-Montgomery-te Riele table forms an extension to the Cunningham tables, for 13 < b < 1000."
The above sentence from the article should apparently read "... for 13 ≤ b < 100." but I am not confident enough to edit the article. (Notice the less-than-OR-EQUAL-TO sign.)
(See http://wwwmaths.anu.edu.au/~brent/factors.html, the apparently current version of the Brent-Montgomery-te Riele tables, and please remove this bit of discussion if you either edit the actual article accordingly or find this analysis flawed.)
- You are of course right; they didn't skip base 13. I've changed it. Ntsimp (talk) 15:46, 17 November 2007 (UTC)

Formula for b^n+1
[edit]I have a problem with the formula b^n + 1 = product_{ d|2n, d!|n} Φ_d(b). Obviously d=1 is always a solution, but for b=2 it does not give a factor since Φ_1(2) = 2-1 = 1 (if I assume correctly that Φ are the cyclotomic polynomials). For n = 1,2,3,4,5,6,... the d's > 1 are {},{2},{},{2},{},{2,3},... repeating periodically up to 24 which has an additional 4. But this would mean that 2^1+1 = 2^3+1 = 2^5+1 etc, which is obviously wrong. — MFH:Talk 22:36, 19 November 2018 (UTC)
Broken links to references
[edit]The links in references are all(!) broken. I could not find available versions of the documents: the relevant page on ams.org does not allow to d/L the Brillhart et al paper. I will change some links to "DOI" which should not rot as fast, but if s/o knows better sources (preprint server etc) PLEASE add it! - — MFH:Talk 23:37, 19 November 2018 (UTC)
