Features Extended:

Really digressing, note that 60 and 360 are highly composite numbers. "A highly composite number (HCN) is a positive integer with more divisors than any smaller positive integer has" (Wikipedia: highly composite number). The HCNs run: (1) 1, (2) 2, (3) 4, (4) 6, (5) 12, (6) 24, (7) 36, (8) 48, (9) 60, (10) 120, (11) 180, (12) 240, (13) 360, (14) 720 (15) 840, (16) 1260, (17) 1680, (18) 2520, (19) 5040, (20) 7560, (21) 10080 ...
Really digressing again, note that
```
   1170/360 = ∑_(n=1)^(24)(1/divisor_n) 
```
which is an expansion in unit fractions that are 1 over the divisors of 360. The ancient Egyptian mathematicians liked expanding their fractions in unit fractions because they seemed to think of unit fractions as more fundamental.
