Sprouts Notation

Is there a standard notation for sprouts? If not, I propose that the dots be numbered from 1 to n and that each generated dot be numbered consecutively thereafter. Let the basic form be ab,c, where a is the number of the newly generated dot, b is "from" and c is "to". 91,2 means a move from dot 1 to dot 2, generating dot 9. If necessary, follow this basic form with a list of enclosed dots delimited by slashes. 91,2/3/ means a move from dot 1 to dot 2 which separates dot 3 from some other dot(s). If the move is still ambiguous, add an @ followed by a dot which the newly generated dot communicates with. 91,2/3/@4 means a move from dot 1 to dot 2 generating dot 9, separating dot 3 from any other previously accessible dots and placing dot 9 in a position such that dot 9 and dot 4 are mutually accessible. I suggest that the first move of a game be prefixed by N (sprouts) or O (reverse sprouts), that moves be separated by semicolons, that all commentary be placed in square brackets, and that a game suffix be :X (win by player 1) or :Y. I also suggest that parsimony and low numbers be given priority. e.g. N71,2; 81,1/3,4/; 92,8; 102,7@ [bad move]; 119,10 :X
