I have placed online a sedenion product calculator written in javascript. I also have placed online a calculator for computing the product of any two Cayley-Dickson basis vectors up to the one-millionth basis vector.

The sedenion calculator is at jwbales.us/sedenion.html and the Cayley-Dickson basis vector multiplier is at the main site jwbales.us/index.html It is based on my soon to be published paper "A tree for computing the Cayley-Dickson twist."

Both pages render better in Firefox than in Internet Explorer.
