TITLE: What are some examples of journals that will accept undergraduate student research?
QUESTION [9 upvotes]: I am currently doing a research project with a professor and 3 other students in an area that is usually seen as a "recreational" math topic; that of change-ringing and its relation to group theory. The papers regarding change-ringing that I have managed to find on JSTOR are generally of an expository nature, and since we do have one or two somewhat original results (we were trying to see what subgroups of Sn can be enumerated using transformations allowed under the restrictions of change-ringing), I think we might have something at least worth trying to submit to a small journal. 
Does anyone have any recommendations?

REPLY [3 votes]: I haven't seen mentioned the AMS undergraduate mathematics page, in particular the "Clubs, Conferences, Events, Online Journals" section. The section mentions the following journals targeting undergraduates:

 Involve, mentioned in another answer.
 The Rose-Hulman Institute of Technology Undergraduate Mathematics Journal, which requires an established mathematician to sponsor your submission and recommend referees.
 The Harvard College Mathematics Review, focuses on expository articles by undergraduates. It also sadly seems to be semi-defunct, the website promises an issue in March but one has not yet appeared.

There is also a new undergraduate journal The Waterloo Mathematics Review from the University of Waterloo (full disclosure: I am one of the editors) in a similar style to the HCMR, though it also accepts original research. We are currently accepting submissions for our second issue, while this answer may find you too late I hope you consider submitting.
