How do we incorporate third order derivatives in 'P3dc' element to solve biharmonic problems?

I was trying to implement discontinuous Galerkin finite element method to solve biharmonic problem. I have successfully implemented dG method to solve biharmonic problem using 'P2dc' element. But it seems that 'P3dc' element does not support third order derivatives in the code. The third order derivative is very necessary for the weak formulation. Can someone please help me how to overcome this shortcomings?
