D4h site symmetry is used to group species into genera
====
 
family= 3 0 0 0
 
family= 3 0 0 0 new D4h genus #     1 with    24 species is 0:1:2
Nber of genera for this family=    1
 
family= 2 1 0 0
 
family= 2 1 0 0 new D4h genus #     1 with    24 species is 0:1:2,3
family= 2 1 0 0 new D4h genus #     2 with    12 species is 0:2:1,3
Nber of genera for this family=    2
