Lumps of muck (or LoM) is a term used to describe the common evolutionary sequence that leads to the blockade. It generally refers to any stage in the evolution of the stairstep hexomino. From the stairstep hexomino, it stabilizes in 63 generations.
While the lumps of muck sequence can be catalysed, it does not have many uses in conduits. There are many oscillators that hassle lumps of muck, though. One particular catalyst can be used as a 5c/9 wire signal injector; see p47 lumps of muck hassler for the specific catalyst.
A six-cell, five-generation predecessor of the stairstep hexomino is shown below to the left. To the right is a hexomino that converges to the lumps of muck sequence in generation 7, and generation 3 of the stairstep hexomino. A significant number of natural occurrences of lumps of muck form this way, only gaining rotational symmetry in its 12-cell form.
Above are common formations equivalent to the lumps of muck sequence. Patterns in the same row are in the same generation. To follow an evolutionary sequence, start from the bottom and move up; if there is nothing above a pattern, its evolutionary sequence converges with the closest column inward that has a pattern until they all reach the top.
