| # --description--
 | |
| 
 | |
| Let R(a, b, c) be the maximum area covered by three non-overlapping circles inside a triangle with edge lengths a, b and c.
 | |
| 
 | |
| Let S(n) be the average value of R(a, b, c) over all integer triplets (a, b, c) such that 1 ≤ a ≤ b ≤ c < a + b ≤ n
 | |
| 
 | |
| You are given S(2) = R(1, 1, 1) ≈ 0.31998, S(5) ≈ 1.25899.
 | |
| 
 | |
| Find S(1803) rounded to 5 decimal places behind the decimal point.
 | |

| # --hints--
 | |
| 
 | |
| `euler476()` should return 110242.87794.
 | |
| 
 | |
| ```js
 | |
| assert.strictEqual(euler476(), 110242.87794);
 | |
| ```
