Hi Juha,

 

I am sorry I don't understand. Can you give a couple of positions which are
not PG, but which show the symmetries you are looking for?

 

And do the PGs have to have odd number of moves?

 

Thanks,
Andrew.

Challenge:

Find the shortest possible Circe PG to symmetric position (to the starting
position).
a) vertical symmetry
b) horizontal symmetry
[c) point symmetry] might be nice also, but probably it's almost like b)
