In the tracking for solvers for the new MagicTile vs 2 we have also place for non-monster puzzles.
These small puzzles are not automatically much simpler. The have clearly fewer pieces but often often not enough place to construct narrow sequences. I take as an example puzzle 1 := the spherical tetrahedron edge turning E 1:0:0. My method consists allways to search a small but sufficient set of sequences (SSSS) for the solving "with many twists". The normal Rubik’s Cube has typically 4 sequences: a 3 cycle foredges, a 3 cycle for corners, a rotator on place for edges and a rotator on place for corners. The opposite is having a large set of small sequences (LSSS; for solves "with minimal twist number"). For puzzle 1 I have found using blindly commutators of commutators one macro which moves only corners (a double switch where no corner stays fixed) and a macro which moves only inner faces (a double switch where no inner face stays fixed). I have no macro for edges only and no macro for outer faces only. I have no 3 cycles, no rotators.
Nan you certainly don’t use SSSS for small puzzles. Can you nevertheless tell us how you construct a sequence for outer faces or for edges in puzzle 1?
