| Oct 7, 2021 at 5:58 | comment | added | Yijapod | @don bright You are right. I don't remember how I did the checking | |
| Oct 7, 2021 at 5:30 | comment | added | don bright | @Yijapod it seems to me like your example -0b01010 0b01000 is -e1e3*e3 .. why is that not -e1*1 and then just -e1 ? if you look at the Cayley table that you linked on bivector.net we can see that e1e3e3 should become e13e3, which becomes e1. which i would think that means means -e1e3 e3 should become -e1 | |

| Sep 27, 2021 at 7:36 | comment | added | G B | @Yijapod: Then probably all signs are inverted because the parameters are given in inverted order. Hard to tell what's wrong when there is no clear test case to check. | |

I think you can just do w*x*(-1)**...
