Wow Tristan,
It only took what, about 5 months. I originally wondered if this problem was related to a HS course. I thought that knowing what course would really help. I think that Larry's answer is probably the one originally sought. I'm trying to figure out what direction you took on this.
I doubt I'm up to the task, but the apparent clues are "Related Numbers" and "most elagant". No luck yet, but I'm gonna kick it around some more.
Thanks for submitting it.
