Working on a 3D analog to 2D Schröder rectangulations, also called
3D *guillotine partitions*.

1 slice, 3 ways:

(The ghostly dots are the points {1,1,1}, {2,2,2}, … that make up the slice points.)

2 slices, 15 ways (removing 3 duplicates from the 18 total):

3 slices, 93 ways (removing duplicates from the 162 total):

4 slices, 645 ways (removing duplicates from the 1,944 total):

After that, the counts are 4791, 37275, 299865, …, counted by OEIS sequence A103210.

A random selection of the 4,791 5-slices:

And a random selection of the 32,275 6-slices:
