How many fields are there (Up to isomorphism) with exactly 6 elements? In case of Group of order 6.. number of group( up to isomorphism )is 2..but what is it in case of field?

1Also, please do some research before posting. The second google hit for "finite field order" is the question I linked to above, and the first hit is a Wikipedia article that cites the exact same result.... – Sep 05 '17 at 15:38

@Jyrki Lahtonen ♦ ; why my flags does not count ? I have raised too many flags but it's about a week none of them has been counted, what's wrong with my account? – Davood Sep 05 '17 at 15:51

I don't know @Famke. The last one I see in your flagging history is dated August 26. I will check with the other mods. May be they know something I don't? – Jyrki Lahtonen Sep 05 '17 at 16:04

@Famke: A piece of news from a fellow mod. A user with 3k rep no longer casts close flags. They are automatically converted to votes to close. – Jyrki Lahtonen Sep 05 '17 at 17:55

The order of a finite field must be a power of a prime, so there are no fields with $6=2\times3$ elements.

1You might want to add that all finite fields with given order are isomorphic. – Bernard Sep 05 '17 at 15:37
