I know you've been in the music business for a few hundred years, Josquin, but there's no need to be so harsh about this undergrad poster! From what I could figure, it's something like a final project for a class on Mathematics and Music at UW Eau Claire. The background material on transformations of sets of pitch classes is in the course textbook. (This doesn't take away from all the citations you helpfully provided, though.)

If it's an undergrad project, it absolutely should cite properly; so that is at least worth pointing out.

To be fair though, posters are often a bit sloppy this way, and in context supposed to be supported other ways.

It's a one page summary with pictures rather than a research paper or such like. There's quite likely some article with sources elsewhere.

It's a scientific poster layout, very standard. They typically have some citation, but only major ones.
