    _______
   /G     H\d
  /         \
 /L         I\c___
 \           /c
  \         /?
   \K_____J/b  
   /A     B\j

 \           /i
  \         /
   \E_____D/h
   /g     h\

after quaring it a litle

e...h
|   |
G...H-d
.....
L...I-c
.....
K...J-b
A...B-j
.....
F...C-i
.....
E...D-h

this is a simplest y wraps and a reversed x wraps.

exact te some wraping as in quincutial on a rec for the canonical map

But you can't tile it on the space with the shape of hex. zones as ??
are viewed in 2 diff way from side I-J and from side C-B
