</span>Yes, AutoConnect will still remove outgoing connections that it thinks<br>
are redundant. So even if the initial ConnectTo's will cause nodes to<br>
connect to the yellow ones, after a while they can remove those.<br>

</span>If you make the yellow nodes ConnectTo all other nodes, and not have<br>
AutoConnect = yes, and the other nodes just have AutoConnect = yes but<br>
no ConnectTo's, then you will get the desired graph.<br>

</span>I should've elaborated here.<br>
