Some Thoughts A start, perhaps? Comment 2 of 2 |
(In reply to D2? by Richard)

I have no idea if this helps, but looking at it quickly it seems that:

  • c = 3k, where k is an integer
  • d = 6n, where n is an integer
I'm not sure if that is correct and/or useful information, I'll try to work it out on paper and see where it goes from there...

*Edited to fix a mistake I'd made...I haven't had a shot to really delve into this one, but I'm surprised there are no other it really that hard?
