Good rigorous intro combinatorics textbook?

[dh363]

Hey guys,
I'm thinking of self studying some math this summer, and combinatorics is one field I never really got into but want to learn a bit of. I rigorous proof experience from reading other books/taking rigorous classes, so I wanted to start off with something relatively rigorous.

Thanks

Cameron's Combinatorics is very good if you already have some familiarity with the basics (counting, recurrence relations, etc.) It doesn't really demand much in the way of prerequisites, but you do have to be comfortable with mathematics in general.

Thanks! That's exactly what I was looking for. Something that assumed a level of mathematical maturity but not necessarily a lot of prerequisites within combinatorics.
