Synchronicity strikes!  At the same minute, I received this email from
the author of the arXiv paper which Ray Chandler helped me determine
had a typo, and Martin Fuller corrected and simplified the formulae:

Dear Jonathan Vos Post,

Thank you so very much for your letter.  You are quite right, and I
have incorporated the correction/simplification into my preprint.  It
should appear on lanl.xxx on Monday.

I am very grateful for the trouble you took and, as a naturally
prejudiced author, I thank you for your kind words about my other preprints.

The paper on semiregular polyhedra will appear in Elemente der
Mathematik...it has been accepted for publication as part of the
"Euler year."

The paper on "The Probability of a Run" was published in the March,
2007,  issue of the Mathematical Gazette.

Finally, the paper on the accuracy or Ramanujan's approximation to the
arc length of an ellipse was published in the online journal JIPAM
(Journal of Inequalities in Pure and Applied Mathematics) in January
of 2006.

I would be delighted to join into any further dialogue about the paper.

Again, thank you very much.

Sincerely yours,
MARK B. VILLARINO
