 | 50 | Path buffer / Minkowski sum | Robot radius 0.5 m along polyline (0,0)→(2,1)→(4,1). Is 1 m-wide corridor enough? | Buffer polyline by radius and check narrowest segment. | [prompt 50](results/prompt_50.md) | 🦖♊️🐋🤖 |
 | 51 | 3-D rotation of extrusion | Equilateral Δ side 6 cm extruded 10 cm (+z). Rotate prism 90° about y. New coords of (0,0,0). | Apply y-axis rotation to 3-D vertex; mixes extrusion + rotation. | [prompt 51](results/prompt_51.md) | 🐋 |
 | 52 | Spatial algorithm design | Two random L-tetrominoes on 4×4 grids. Outline algorithm (no reflection) to test rotational equivalence. | Meta-spatial reasoning, not brute enumeration. | [prompt 52](results/prompt_52.md) | not evaluated yet |
-| 53 | Mirror-vs-rotation (ASCII) | Block letter “G”: rotate 90° CW, then mirror across vertical axis. Draw final glyph. | Rotation-plus-mirror decoy; many swap the order. | [prompt 53](results/prompt_53.md) |

 | 54 | Out-of-plane flip (ASCII) | Cardboard “E” flipped 180° about horizontal axis. ASCII-draw result. | Requires 3-D mental flip, not 2-D mirror. | [prompt 54](results/prompt_54.md) |
 | 55 | Shear + rotation outline | Shear x' = x + 0.5y on 5×3 box, then rotate 90° CCW; ASCII outline. | Compound linear transform (shear then rotate). | [prompt 55](results/prompt_55.md) |
 | 56 | Diagonal mirror with punch | 6×6 ASCII square with hole (1,4); reflect across y = x; draw. | Forces mapping of interior point through diagonal mirror. | [prompt 56](results/prompt_56.md) |
