In a excellet review paper (see below [1]) Shuangzhe Liu & Götz Trenkler show 
some results on matrix products:

- Hadamard product
- Kroneker product
- Khatri-Rao product
- Tracy-Sigh product
- Khatri-Rao sum
- Tracy-Sigh sum
- Vector cross productSchur complement, etc.

With this  thread, we intend to create a collaborative work to find the 
J-expressions that meet these products and sums. 
If you want to collaborate, these will be published in next issue of Journal of 
J (deadline May-31)
Thanks in advance,
Mikel
