Read the background

For every positive integer n outside {2,4,9}, some irreducible complex representation of Sₙ has a tensor square containing every irreducible complex representation of Sₙ.

Why it matters

If correct, resolves the universal tensor-square conjecture for every possible symmetric-group degree.

What counts as progress

Does every symmetric group outside the known exceptions have a universal irreducible tensor square?
