This symmetry pattern is established with 6 cu and its multiples of 12 cu and 18 cu. The sum of the two oddballs, 26 cu and 76 cu, add up to 102 cu (17x6 cu).

### 161

The main symmetry element in this chart is 5 cu and its multiples, with one 6 cu and one 56 cu to complete the ring.

162

10 cu is the element that brings out this symmetry pattern. One lone 32 cu is necessary to complete the ring.

### 163

The angular number that imparts symmetry to this pattern is of course 6 cu, with its multiple of 12 cu (2x6 cu). #94 was added as a point of interest to indicate a possible center for the small elliptical projection of #99.

### 164

4 cu, with its multiples of 8 cu and 16 cu, gives us this symmetry pattern.

### 165

The hard core of this symmetry pattern was set up with #103, #99, #93, and #88-the rest are for interest only. The symmetry pattern is obviously based on 11 cu.

### 166

The symmetry pattern is based on 4 cu and 6 cu.

### 167

This is an example of bilateral symmetry with the 10 cu centerpiece being flanked on each side separately by two 8 cu and one 18 cu. #104 is an uncertain position, but it was entered as a possibility.
