Problem statement

Accourding to a classical theorem by Wall, any two homotopoy equivalent, simply connected smooth closed 44-manifolds XX and YY become diffeomorphic after stabilizing by taking connected sums with some number of S1×S2S^1\times S^2's. What does it says about trisections of the trivial group?
