Hi ab Yes youve got the hang!!
Of course there are only one solution to L(2,3) and L(2,4)
I see that your three solutions for L(2,7) are at the top end of the search spectrum.
(7 right on the edge)
Are you using a search program???
I used to build Basic programs for this sort of thing But my Windows 7 wont support Basic and I cant get the hang of Macros.
Am at present delving into L(2,8) "with pencil paper and fingers.!!!!!
Thanks for your post.
At least I am not alone.
Some interesting pics deep in/on the net.
