Wikipedia User talk:Dominus/Archive (2009) Parasitic Numbers vs. Palintiples Actually, I don't believe I did anything on Parasitic numbers. I think you're remembering Palintiples, numbers that can be multiplied by an integer by reversing their digits. If you consider them encyclopedic, go boldly. I suspect that as nearly* the only source of original research on the subject, it would be in poor taste for me to edit on the subject, but GIYF. (*)There's some intriguing related work by L. A. Graham, probably in The Surprise Attack in Mathematical Puzzles. I suppose I could edit on that if desired. -Dan Hoey 01:26, 23 October 2009 (UTC)
