In dual-direction network, it shows: the value of network relates to the square of user number.

Let P is an odd prime, in this paper we prove that the maximal square free number Q ( 2p-1) of Mersenne numbers 2p-1 satisfies: Q ( 2p-1)≥ min ( 2p-1,(π P/ logp) 2)

设P是奇素数，本文证明了：Mersenne数2p-1的最大无平方部分Q（2p-1）满足：Q（2p－1）≥min（2p－1，（πp／logp）2）。
