In my presentation I tried to emphasize the conceptual aspects. There are several ways to approach the octahedral axiom, and in my experience several people prefers different presentations to grasp it better. | |

This forces the category to be graded: it has to have an automorphism, called "shift" or "suspension", denoted most frequently as $X[1]$ or $\Sigma X$" can you explain what do you mean by shift of degree | |
