Zhdanov and Jagondzinski
« on: May 21, 2009, 06:55:00 AM »
I'm trying to understand how to derive Zhdanov and Jagondzinski symbols for close-packed polytypes, but I just don't get it.

Example:

...ABACACBCB...

Jagodzinski: hhc
Zhdanov: (21)

Anyone who can explain how the above results are derived?
