Jun 14, 2014 at 21:29 comment added Kieren MacMillan So the proofs (and included parameterizations) by Bradley (jstor.org/stable/3620159) and Barnett (jstor.org/stable/2302941) are false? Or is it just not possible to reduce their general parameterization(s) $A^2+B^2=C^2+D^2+E^2$ to the special case $e = \pm1$?
