To make the TT~T state with non-zero relative momentum as the leading exponential: we impose anti-periodic boundary condition on the pion, which is implemented by imposing G-parity or H-parity on the quark fields at the boundary. With this, we calculate the I = 2 7r7r phase shift from lattice simula
