Understand

We obtain the exact analytic form of the growth index at present epoch ($a=1$) in a flat universe with the cosmological constant ({\it i.e.} the dark energy with its equation of state $\omega_{de} = -1$).

For the cosmological constant, we obtain the exact value of the current growth index parameter $\gamma = 0.5547$, which is very close to the well known value 6/11.
We also obtain the exact analytic solution of the growth factor for $\omega_{de}$ = -1/3 or -1.
We investigate the growth index and its parameter at any epoch with this exact solution.
