Product Parade by Anteater

• Normal sudoku rules apply.
• For each green dot, the product of the digits in two of the four surrounding cells equals the product of the digits in the other two surrounding cells. These two pairs of cells may be arranged in any fashion around the dot. For any two distinct green dots, these products of pairs must be different. Not all possible locations for green dots are necessarily marked, and the requirement for products to be different applies only to those that are marked.
• Digits separated by a white dot differ by 1. Not all possible locations for white dots are necessarily marked.
