Hi all
In order to avoid the confusion of the order of 6js, the description
in appendix C of "Me'canique Quantique" by Albert Messiah is helpful.
Each side of a tetragon in 3D, with four surfaces, is correspond to the j
values and the face two sides in a column of 6j-symbol. (not reactangle in
2D, sorry for miss using the last mail)
see Fig C.2 in Messiah
(It is not easy to draw the tetrapack using asci code)
{ ja, jb, je }
jd, jc, jf
__jb__
/ \
ja/ \jd
/___________\
jc
ja + jb = je
jb + jd = jf
