Blashyrkh made a puzzle, called The Parker Miracle, referring to the (in)famous numberphile video about the Parker Square. So why is this not a Parker Miracle. It doesn't need the inequality sign to get a unique solution. The sign is only a catalyst. Without it though, there is no logical solving path (I could find.) So maybe it is a Parker Miracle, maybe it's just the treachery of words.

• normal Sudoku: Put the digits 1-9 once in each row, column and region.
• An inequality sign points to the lower digit.
• In each box, the box number is in its relative box position.
• Digits that equal the row number, equal the column number.
• Orthogonally adjacent digits are not consecutive.
