Sam Elder, at MIT, has made impressive progress
on this subject, which Phil Carmody and I studied
on this list, with algorithmic help from Makoto Kamada.
Sam's article references this list:
 D. Broadhurst, Cyclotomic polynomials puzzles, Yahoo Groups primenumbers message #20282,
 D. Broadhurst, Flat ternary cyclotomic polynomials, Yahoo Groups primenumbers message #20305,
but it is also important to record, here, the interaction
with Phil and Makoto, on this list, that informed my work.
Sometimes, maths authors are reluctant to reference our
amateur musings, in PrimeNumbers. Sam took the opposite view.
