I have called this configuration of
12 variable pentagons a
"pentanon"...in that it is a nine-
sided object made up of pentagons.

Pentanons are combined to
construct pentanon spheres.
Though usually they are modified, in
some way to fit the symmetry of
the construction.

Pentanons of PS903, for instance,
share two pentagons where
pentanons overlap.
