Yes, in fact almost all of the hard puzzles with this pattern will have a form of "SK Loop". I believe the 16 clue base [313,1x1,313] from which all these types of puzzles [ 313,161,313] were cloned have the initial SK loop eliminations. There are SK loop eliminations - and they arise only using the 16 clues - and that is why the 16 clue base has 200,000 - 800,000 grid solultions. [no clue insertions][random 16 clue has at least 4 million]
