Yeah, and this works for any "algebra" (ie. vector space with a way of multiplying vectors.) The three legged thing is what they call the "structure constants"

- _Microft 7y agoWould it make sense/work to do something like this ? (a x b )(c x d) => ??? o o o o \ / \ / o - o => o / \ / \ o o o o Would the circle in the middle of the cross be a tensor of order 4 then? Edit: It's been a while since I did that but wouldn't that be the following in sum notation? eps_ijk a_j b_k eps_ilm c_l d_m = (new tensor)_jklm a_j b_k c_l d_m
- mathgenius 7y agoYes it really is just like lego, you can make all kinds of bizarro shapes.
