As rows, columns, digits can be switched each other to make isomorphic puzzles that "look quite different", only one of each equivalence class is shown.

If no extra marks, the puzzles can be solved by Pairs, X-wings and 5-step chains.

When a grid has multiple automorphisms, number of automorphisms is marked(titled "Symmetry"), including identity transformation.

The puzzle grids are after singles and normalization(shape first, then digits)
