In this paper, we present the preliminary study of the formulation of fractional explicit group (FEG) and fractional explicit de-coupled group (FEDG) iterative methods in solving the two dimensional second order diffusion wave equation of fractional order. Both FEG and FEDG iterative methods are derived from the fractional standard and fractional rotated five points Crank-Nicolson discretizations respectively. Their computational complexity is presented and numerical experiments are conducted to demonstrate the efficiency and adeptness of the newly developed explicit group formulations in terms of CPU timings and total number of operations.
