I know the notation from LR(0) machine construction, but also know
that Gluskhov used it in his solution to NFA construction.  Earley
also used the notation to describe his method if I understand right.
I'm presuming that there is some first use of the notation.  Do we
know who invented it?

Thanks in advance,
Chris
