Specific heat and transport properties are measured on good single crystals of SmB6. The specific heat experiment indicates that there is a gap of near 100 K in the 4f system leaving a very small T linear term. Conductivity experiment indicates that the usual hopping type conductivity changes to a constant value without activation which is, however, three orders of magnitude smaller than the so far believed minimum metallic conductivity. The usual Anderson localization proposed before by us is clearly not applicable. Here, we propose a model of a new type of the Wigner lattice formation. Various anomalous properties mentioned above are explained within this model
