Considering this portion of the zone [lOll : 0221 : 1120] the major 

 zone intersection suggests the pole (1232) = (211) as a knot. Split- 

 ting the zone at this point and developing the first half, we have for 

 the forms recorded between (lOll) = (100) and (1232) = 2lT): 



Referred to N3 this zone fragment is somewhat incomplete and con- 

 tains the extra form g.
