摘要：
We consider a new modified gravity model with nonlocal term of the form R-1 F(square)R. This kind of nonlocality is motivated by investigation of applicability of a few unusual ansatze to obtain some exact cosmological solutions. In particular, we find attractive and useful quadratic ansatz square R = qR(2).
