doesn't give a nice term for its center. The best plan I've come
up with so far is to call the boundary of this circle the "(Guinard)
Ring", and its center "the Ring center, R", and to keep "Arena",
since after all that's a good word for what's inside a ring.
I may have forgotten to alert Hyacinthians to the fact that
some conjectures I made about the loci of In and Is turned
out to be false. These loci aren't in fact the standard Arena
and its complement, but are interestingly related to them. I
was meaning to work out the exact details, but didn't yet get
around to it.
Can someone (Antreas or Paul?) please send me the barycentrics
for the focus of the Kiepert parabola? I want to "locate" it,
and in particular, to see if there's some nice relation to the
center of his hyperbola, namely the infraSteiner point iS,
which I recently did locate, as the Ring-inverse of K. I have
an idea that the parallel to the Euler line through either the
Kiepert focus or the Kiepert vertex should go through some
Thanks in advance,
