Publishing elementary results
From your description it sounds like the results have no implications, no relation to other problems, and is not significant in any way beyond that paper. In that case, chances are journals will not accept the paper. A paper needs to convince the editors &amp; reviewers that its results are actually interesting.
Check out Steven Gubkin's answer to another question:

Here is a brand new mathematical theory I have invented just now (in the last 30 seconds):
A Gobleflump is a set together with a ternary operation Star(a,b,c), and a binary operation Spade(a,b) satisfying Star(Spade(a,b),Spade(c,d),Spade(e,f)) = Spade(Star(a,b,c),Star(d,e,f)).
I could now devote my life to the study of Gobleflumps. I could publish papers about extremely regular gobleflumps, and the equivalence between hyperconvex gobleflumps and hypoconvex grendleflops. This might all be legitimate, correct mathematics.
No one will ever care about my lifes work, or probably even read it, unless it makes some connection to existing mathematical theory, illuminates why something disconnected from the theory works the way it does, or solves some existing problem.

... and if no one will ever care about the results, most reputable journals will not publish them, either.
