Two manhole covers, both with five segmented rings and a center, were seen in the street beneath our feet.
 |
| 8x8x8x8x8 with raised center |
That manhole cover has 8 x 8 x 8 x 8 x 8 segments per ring, label with a raised center, and with vent holes in the second ring.
 |
| 12x12x12x6x6 and depressed center |
This manhole cover has 12 x 12 x 12 x 6 x 6 segments per ring and a depressed center.
The five rings make them look similar, but counting the segments per ring shows them to be different.
