Imagine a honeycomb-like structure of hexagons, then turn it on its side. Now suppose instead of open cells, assume each cell is a solid masonry casting (a brick). While the structural properties and related good practices for rectangular brick assembled into walls and piles are well-known, I cannot find anything comparable for single or multiple adjacent walls of vertically-oriented hexagonal bricks, or guidance for enclosures and/or bracing to assure they will not fall down.
So, my question is: what is known about building and assuring the stability of such a structure?
Thanks in advance for links/cites for pertinent publications and any other insights, case studies, heuristics, stories, etc.
