Applying rectification onto either of x3-4-o2-3-o2 or x2-3-o2-4-o3 in the respectively other direction each, re-uses the former edge counts for new vertex count, and uses the duals of the faces each (somewhere further out) as the two face types in here. Alternatively those additional face types could be obtained as the respective vertex figures of the pre-images each. Edges themselves in here are 2-fold, as can be read from the symbol directly, i.e. are down to real ones again.
