I know, this sequence of titles looks like that terrible movies Cube and Cube 2: Hypercube (I apologize to those who liked them...), but Prof. Caticha answered my email and, as I predicted, there is a more elegant formula for expressing the

Also, changing the notation of the unity matrices such that

Well, I have nothing specific to speak this week, but I was browsing the arXiv and found some odd papers. What I mean is that they have curious titles, but I really still haven't read them to say something about their contents. I'm listing them here if someone wants to check. :)

and also some news:

*n*-cubes algebraically. It is not to much different from the one I posted, but I will describe it anyway. Instead of initiating with the representation of the 1-cube as I showed in the last post, you can initiate it by representing the 1-cube as the Pauli matrixAlso, changing the notation of the unity matrices such that

*I_n*is the*(n+1)x(n+1)*unity matrix just to make the final formula prettier and following exactly the same procedure as before, the expression for the*n*-cube becomesWell, I have nothing specific to speak this week, but I was browsing the arXiv and found some odd papers.

What does the little sigma mean?
