minimal perimeter of a polyhex

[Tanya Khovanova]

Dear SeqFans,

I just submitted the sequence:

6, 10, 12, 14, 16, 18, 18, 20, 22, 22, 24, 24,
Minimal perimeter of a polyhex with n cells.

I am surprised that this sequence wasn't there.

I calculated it manually. Anyone has a program dealing with polyhexes?
Can someone extend it? Is there are program for polyhexes somewhere
available for free use?

Best, Tanya
