Note: 



1 . Mark on each pentagon the pentagon number at center 

 and angle numbers at edge. These numbers should be 

 maintained throughout fabrication of complete sphere. 



2. Angles 0-| through 04 are angles through center of sphere. 



3. Angles 0-j through 0-jq are measured from the center of 

 pentagon. 



4. Ar denotes change in internal surface curvature from 

 specified 7.000 inches; + indicates shorter radius, while 

 - indicates longer radius.
