The 2 + 1 dimemsional Kaup-Kuperschmidt (KK) equation is considered. A bilinear form of the equation is found and then 3-soliton solutions are obtained with the assistance of Mathematica. Six symmetries of the bilinear 2 + 1 dimensional KK eaution are given and their symmetry algebra is identified.
