||
4 | #D A p150 gun fires at a pair of pentadecathlons. When the first glider |
||
5 | #D hits the PDs, it is reflected back and hits the second, forming a |
||
6 | #D honey farm. Subsequent gliders form a crystal growing upstream. When |
||
7 | #D the crystal reaches an eater near the gun, it begins to decay. |
||
8 | #D When it's all gone, the cycle begins again. |
||
9 | #D |
||
10 | #D The period of this pattern is 2700, but by moving the PDs, any period |
||
11 | #D of the form 750 + 1950n (n>=0) can be obtained. |
