Instruction:
Place a number from the provided set into each (square) cell so that each number appears at most once (but possibly zero times) in each row and column. Some groups of numbers are surrounded with ovals along rows and columns; those ovals should be considered to represent multi-digit numbers, reading the squared numbers from left-to-right (for rows) or top-to-bottom (for columns). Multi-digit numbers may not start with 0.
Some cells and/or ovals are connected with arrows. A dotted arrow points from a smaller number to a larger number (the two numbers may not be equal). A solid arrow points from a number to a positive multiple of that number (the two numbers are allowed to be equal, but neither number can be 0).
