For symmetric 6-couple rectangular choreography, there are 64 possible sequence states.

The state is indicated as two numbers separated by a dash (e.g., B-G), where B indicates the boy's state, and G indicates the girl's state.

Values for B and G:

	 0  -->  in sequence.

	14  -->  1 and 4 swapped.
	25  -->  2 and 5 swapped.
	36  -->  3 and 6 swapped.

	12  -->  1 and 2 swapped.  (also 4 and 5).
	13  -->  1 and 3 swapped.  (also 4 and 6).
	23  -->  2 and 3 swapped.  (also 5 and 6).
	34  -->  3 and 4 swapped.  (also 6 and 1).

	88  -->  asymmetric.
	99  -->  unable to determine sequence.
