Characteristics of the quasi-bound state in the K(-)pp system strongly depend on the model of antikaon-nucleon interaction and weakly-on the nucleon-nucleon potential. In the present paper, dynamically exact Faddeev-type calculations with coupled K-N N and pi Sigma N were performed using different models of the Sigma N and pi N interactions to study the influence of these 'less important' interactions on the three-body result. In addition, dynamically exact three-body Faddeev-type AGS calculations with three coupled particle channels K-N N -pi Sigma N-pi Lambda N were performed.
