Registration of&-edra S-acra. 

 Table A. 



1. One zoned triaxine, having three amphigrammic axes, whose 

 poles and zones are read below in Table B. 



2. Two homozone triaxines, having one a zoned amphigrammic 

 and two zoneless amphiedral, and the other a zoned amphigrammic 

 and two zoneless amphigonal, axes. The poles and zones are written 

 below in Table B. 



3. One 7-zoned monaxine heteroid, viz. the pyramid on 7-gonal 

 base. 



4. Five 2-ple zoneless monaxine heteroids, with amphigrammic 

 axes. 



5. Eleven monozones, of which 



3 have the zone Z={2, 2, 0, 0},

C. Twenty-two asymmetric 8-edra 8-acra. 



Table B. 



Janal zoneless polar face : 4/ a 47 = 1, 



the zoneless pole of one homozone triaxine. The reciprocal summit 

 is the zoneless pole of the other homozone triaxine.
