I have the following expressions:
R[1, 1] R[2, 1] R[3, 1] R[4, 1]
sum[FF[3, ak[1] - ak[2], 1], EE[2, ak[2] - ak[3], 0], EE[2, ak[3] - ak[4], 0]]
By what procedure can I convert such expressions into expression:
sum[R[1, 1], FF[3, ak[2] - ak[2], 1], R[2, 1] , EE[2, ak[2] - ak[3], 0], R[3, 1] , EE[2, ak[3] - ak[4], 0] , R[4, 1]]
