Hi, I'm an undergrad at Portland State, where we have been learning Sage as part of our Computer Assisted Mathematics Group. We want to compute with octonions in Sage, and discussed at our meeting last night possibly implementing such an algebra.
As I understand it, multiplication of octonions can be implemented on top of the quaternions in a simple way using the Cayley-Dickson construction http://en.wikipedia.org/wiki/Octonion#Cayley-Dickson_construction . The difficulty then would seem to be to do it correctly so that it works with the rest of sage. I'm willing to do it once badly just for fun and then later maybe help with doing it correctly, but I'd like to at least get off to a respectable start. Any help would be greatly appreciated. Oh also in searching for existing implementations I saw that boost has this: http://www.boost.org/doc/html/boost_math/octonions.html but since sage already implements quaternions it seems unnecessary to look at boost except perhaps for inspiration.
