c8.t15.13

**18.10-18.11.** *Arrangement of bricks in the second layer.* In the second layer, the inscribed square is turned such that the corners point towards intermediate directions Fig. 67(b). The square is filled with 144 one-twelfth bricks as before and 24 similar bricks are placed in the segments. The remaining space in each segment is also divided into 7 parts as in the first layer, making their number 28. To avoid overlapping of edges, the *pradhi madhyamā* brick is placed in the handle, and the space below is equally divided. The total number aggregates to 198. The deficit is met by replacing 2 one-twelfth bricks in the square by 4 half bricks.
