Query: The ${}_{\Lambda\Lambda}^{\,\,\,\,4}n$ system   Using local central Yukawa-type Malfliet-Tjon interactions reproducing the
low-energy parameters and phase shifs of the $nn$ system and the latest updates
of the $n\Lambda$ and $\Lambda\Lambda$ Nijmegen ESC08c potentials we study the
possible existence of a ${}_{\Lambda\Lambda}^{\,\,\,\,4}n$ bound state. Our
results indicate that the ${}_{\Lambda\Lambda}^{\,\,\,\,4}n$ is unbound, being
just above threshold. We discuss the role played by the $^1S_0$ $nn$ repulsive
term of the Yukawa-type Malfliet-Tjon interaction.
