A four frequency Class I icosahedral geodesic sphere.
This can be specified as the Class I pattern repeated
according to Fuller's stepping frequency
geodesic -F 4 std_ico | antiview
as the Class I pattern repeated four times along an edge
geodesic -f 4 std_ico | antiview
or as general pattern
geodesic -c 4,0 std_ico | antiview
View this model with the command
geodesic -f 4 std_ico | antiview
