Sokoban lessons - Tiny squares

The figure I like most is what I call "tiny square": four goals connected to form a small square. I've been curious to find out the best and most beautiful "tiny squares", and this is the result, in chronological order.

Excellent! Rotary puzzle, also with a very simple structure, it is necessary to make skillful use of spaces in the cargo room (bottom right). As in the next puzzle of Kenyam, boxes 3 and 4 are placed alone, but this is usual in the puzzles of connected goals.

This is my favorite. Amazing puzzle of remarkable difficulty, but more surprising is its simple structure: two rooms and a side corridor. Not only is the best "tiny square", but one of the best puzzles of four boxes.
