The Picture-Perfect Numbers

Authors: Joseph L. Pe

This paper reports on the research efforts of a group formed in 2002 to work on a problem introduced by the author. The group studied picture-perfect numbers, which are numbers defined using reversal and the usual definition of perfect numbers, and were initially thought to be quite rare. The paper announces the discovery of a remarkable theorem by one of the group's members, Andersen's theorem, that generates a (probable) infinity of PP numbers at large scales.

Comments: 14 Pages. This paper was published in the (now defunct) journal Mathematical Specturm, 40(1), 2008, 40(1), 2008.
