A six frequency Class III icosahedral geodesic sphere.
This can be specified as the particular Class III pattern repeated
according to Fuller's stepping frequency
geodesic -F 6 -c 2,1 std_ico | antiview
as the Class III pattern repeated
twice along an edge
geodesic -f 2 -c 2,1 std_ico | antiview
or using a general pattern
geodesic -c 4,2 std_ico | antiview
View this model with the command
geodesic -F 6 -c 2,1 std_ico | antiview
