     6: 
     7: We shouldn't be using a commutative operation. According to:

     9: Cox, G., Kachergis, G., Recchia, G., & Jones, M. N. (2011).
    10: Towards a scalable holographic word-form representation.
    11: Behavior Research Methods, 43, 602-615.
    12: 
    13: They apply a "random" but invertible permutation before doing the
    14: circular convolution, to force it to be non-commutative.
