Compact connected regular graphs

[jonas.thornvall at gmail.com]

How come all graphs using 42 links and more then 84 nodes have compact  regular connected solutions?

Did turn off animation for more than a couple of thousands of  links so the animation is off when searching but script give message and numerical results on search.
