Hasse diagrams of basic blocks containing four comparable reducible elements and having nullity four

In $2020$, Bhavale and Waphare introduced the concepts of fundamental basic block and basicblock, associated to dismantlable lattices.Further, they have provided the recursive formulae of the number of non-isomorphic fundamental basicblocks as well as basic blocks, containing $r$ comparable reducible elements and having nullity $l$.In this paper, we actually obtain the Hasse diagrams of the basic blocks containing fourcomparable reducible elements and having nullity four.
