Thanks Raphael

I wanted to send an email to you but I did not know your address and  
on your blog, I did not find it.
because I know your interest for the graphs !

Yes my Heawood graph is wrong ... and for icosahedron graph I put a  
bad %
  and after I delete tne comment :(  thanks and bravo !! for the  
correction

I make also a mistake with the names Wheel, Star et Regular the  
evening i put
  a new version 1.3

I did not know LCF notation but I can look at what I can do. Simply,  
I await the next version of Tikz with its library of maths because I  
will be able to improve my algorithms. Moreover I did that for the  
graphs circulating at the end and I hope to more use it for other  
constructions.

Sorry my english is not very good

Greetings Alain

PS :one comment : on your blog the link to my site is wrong !
Do you want that I put  a link to your blog on my site ?
