Detailed Description

A vertical two-site environment consisting of six tensors surrounding those on two neighbouring sites.

The remover tensor is contained in the top corner, but needs to be inserted if either of the two focus sites is the [0,0] site.

Tensors are arranged as:

   -ct-
/   |    \
lt-    -rt
|        |
 
|        |
lb-    -rb
\   |    /
   -cb-
