Changing row 1 to row 2 generates one of the 128 possible Geometric transformations of 4x4 sudoku. Rotations and reflections are also included in these transformations.

Here I leave links to videos where you can see the results of the 128 transformations on a sudoku board as well as on the representation in a tesseract.

The sudoku board is prepared to show all the transformations

Each of the 16 existing templates are located at the vertices of the tesseract. An edge is placed between two templates that can be part of some solution
