With a larger group there are already smaller groups of people talking together and it is hard to approach and invade their discussion for an introvert. And the discussions are also more likely to be presentation style where everyone sits and listens to an expert.
With a smaller group, e.g. meeting around a pub table, you are almost forced to take part, and are a part of the discussion from the beginning.
I greatly prefer the two groups I belong to that have less than 15 people and meet up in pubs, compared to the larger ones, that have good information but are less useful for me for meeting people etc.
