Unresolved cases

Open questions in complex fusion categorification.

What each case record contains

Explore the remaining rings, their categorification status and invariants. Each case shows established obstructions and implications between categorical structures, supporting evidence, and its complete fusion tensor as a Python list.

Unresolved means that general categorifiability is undecided. A surviving necessary condition or unsuccessful search is not a construction.
