Well. It's actually Eric Weisstein; Wolfram the _company_ merely hosts
the site and employs Weisstein. Furthermore, mathworld doesn't invent
this stuff; it makes enormous numbers of references to mathematical
literature, and points out when notations are confused (as they often
are, in mathematics).
We should use the most commonly used terminology, and mimic in our code
what actual mathematicians use, because otherwise we are, for no good
reason, making life difficult for the users of our code.
Making up names is just annoying. This whole thread's turned into a
bikeshed.
Nicolas, you know better than anyone else here what the names should be,
given your training.
