My answer would be no, it is not. For the K-Map, circled numbers may be circled again. You can circle in groups of 2 or 4. Thus you can circle as well slots 6-7 and 7-8 in addition to 3-7. Assuming a numbering from 1-8 of the cells left to right then top to bottom.

re

I agree, you can circle adjacent squares more than once. How many more can you find?
