Hello,

 

I tried implementing anti-commuting variables in my program with the use of physics package:

 Physics[setup](anticommutativeprefix=theta);

Checked that theta is anticommuting:

type(theta_i,anticommutative);

Received true, however computation like:

theta_2 * theta_1 - theta_1 * theta_2 ;

Gives 0, not accounting the anticommuation properly. How can i fix this?
