Effect of connectivity with network size on anti-phase synchronization. Probability of anti-phase synchronization reduces with network size and with degree of connectivity in random graphs. When connectivity is low, AP synchronization is stable for larger sizes. Differences in stability between odd and even sizes are evident. Fully connected even-sized networks are easier to synchronize as partitioning in to two groups is easier than fully connected odd-sized networks odd-sized networks. The odd-even effect reduces with decreasing connectivity.
