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. From: retros-bounces at janko.at [mailto:retros-bounces at janko.at] On Behalf Of Juha Saukkola

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)
