where is an arbitrary constant, and the condition on the variation of the Lagrangian

(4.28)

Next, let us consider the covariance of the field equations of

(4.29)

By calculations similar to (4.25) we find that they transform as

(4.30)

Requiring the covariance we obtain another condition on the variation of the Lagrangian

(4.31)

Now we can find out a possible duality group by studying (4.27), (4.28) and (4.31). Comparing (4.28) and (4.31) we find . Then, the conditions on the parameters (4.27) can be written as
