The point titled in picture as 3+2omega is actually 2+2omega by actual grid position — Preceding unsigned comment added by 88.101.120.235 (talk) 19:39, 4 September 2020 (UTC)
- Look carefully: 3+2omega is correct (omega goes in North-west-ish direction).
Ordinary (rational) integer
"Thus the norm of an Eisenstein integer is always an ordinary (rational) integer."
Isn't every integer already rational? Obscurans 17:43, 12 May 2007 (UTC)
- "Rational integer" is a term of art used to describe the whole numbers in contexts where "integer" may refer to more general algebraic integers. —David Eppstein 18:47, 12 May 2007 (UTC)
Quotient of ℂ by the Eisenstein integers
I wanted to link quotient but I'm far from sure which of the many senses is most appropriate. —Tamfang (talk) 01:06, 30 August 2012 (UTC)
Bad Image
I dont believe the image on the top right of the article is correct. The coordinate labeling seems wrong — Preceding unsigned comment added by 75.172.58.58 (talk) 19:09, 10 November 2012 (UTC)
- What do you reckon it ought to be? —Tamfang (talk) 04:51, 12 November 2012 (UTC)
pictures of Eisenstein primes
I would suggest to include a copy of the picture of Eisenstein primes as can be found on the Quadratic Integers page. Needless to say, I would love to see a larger portion of the plane, as in the picture of the Gaussian primes! — Preceding unsigned comment added by 80.255.246.230 (talk) 12:33, 29 March 2013 (UTC)
