 ;W[j2]C[Peter\: Note that both the f6 group and the e4 group are connected to the a-edge (and therefore to each other). 

Therefore, this situation is equivalent to the template

https\://www.mathstat.dal.ca/~selinger/templates/svg/template-Icj-z-gxc.svg,

which works essentially like the hammock template. The main point is that each of g3 and h4 is separately (but not jointly) connected to the a-edge without needing h3 for the connection.]
