Toric diagram for (a) consists of one vertex. Operators involve a single and have a simple arrow (lower part of (a)), as follows from Figure 9. The correlator (4.1) is translated into a sequence of arrows, with rotated dashed lines representing insertions of interlacing two-dimensional partitions. The resulting figure (b) represents plane partitions crystal model, the same as in Figure 7, but now seen from the bottom.
