dear sir, give me a little time (2 days or 3 days) to give a more detailed demonstration.
but I must know two things if you enjoy: 1) are that I must show that the distance between A and B equals the distance between f (A) and f (B)? 2) are that the algorithm is to explain or not? and thank you On 18 juil, 16:29, Miroslav Balaz <[email protected]> wrote: > Now it is more clear to me. > So labeling of vertex is set of n fourtuples. > > Still i do not understand the proof( first implication trivialy holds, > because such labeling is in variant to permutation) > > 2) A and B have the same labeling. > If the labeling of A in the pseudo-tree x is nhmb, labeling B in the > pseudo-tree is also: n hmb because it af (x) = y. with the same idea > (the automorphism keeps distance), we find that f (A) = B. > > try to explain it in more details. this is not proof.
