I think knowledge of the concepts of group, ring, and field is
supposed to be standard knowledge for any high-school senior -- isn't
this what the "new math" was all about?.  But they're pretty
fundamental to computer science; anyone trying to do serious work in
the field (that is, anyone with a reason to read the PEP) should have
a nodding acquaintance with them.
