As the group getting bigger, the number of connections between members of group getting bigger. This cause slowing down of the process of coordination. If the group will use peer-to-peer equal terms deliberation, the amount of communication time will get bigger exponentially' thus sending the group to an holt. To solve this, groups usually use un-equal methods of deliberation and influence.
The mathematical formula for the number of connection lines in a group is:
cl=((n-1)^2-(n-1))/2
cl = connection lines; n = number of group members
In large numbers we can round up the equation to:
cl=(n^2)/2)
