| # --description--
 | |
| 
 | |
| Consider a honey bee's honeycomb where each cell is a perfect regular hexagon with side length 1.
 | |
| 
 | |
| One particular cell is occupied by the queen bee. For a positive real number L, let B(L) count the cells with distance L from the queen bee cell (all distances are measured from centre to centre); you may assume that the honeycomb is large enough to accommodate for any distance we wish to consider. For example, B(√3) = 6, B(√21) = 12 and B(111 111 111) = 54.
 | |
| 
 | |
| Find the number of L ≤ 5·1011 such that B(L) = 450.

| # --hints--
 | |
| 
 | |
| `euler354()` should return 58065134.
 | |
| 
 | |
| ```js
 | |
| assert.strictEqual(euler354(), 58065134);
 | |
| ```
