Wow, congratulations, Professor Handelman! I just found your paper and will be sure to read it over, if the level of mathematics is accessible enough to me at this point in time. Does your result mean that the NIEP is, in fact, solved for generalized $n$? Or is the problem still open for $n \ge 5$? Most of the literature that I have found so far say this, so I was wondering what you thought. Thanks so much, @DavidHandelman,
