Cayley Table of Elementary Abelian Group $E_8$
$begingroup$
I read about elementary abelian group $E_8$ at https://groupprops.subwiki.org/wiki/Elementary_abelian_group:E8#Definition. I've performed some searches on other sites and have yet to come across a Cayley table for it. Any leads on where to find one?

Why do you need such a huge ($8times 8$) table? As long as you know the definition, you can create the Cayley table if you want.

@EclipseSun Yes, knowledge of the definition should be sufficient to generate the table. I suppose I lack supreme confidence in my execution and would like to verify.

I wouldn't call it E8. The usual notation is $2^3$. E8 tends to refer to a root system.
