Pentagonal symmetry occurs only in biological systems, often combined with hexagons – which usually requires them both to “bend a little.” Inorganic crystals never have pentagonal symmetry. Many “built in constraints.” Steve Gould was an expert on them. Oh the happy memories of structural biology!

Geometry always was my favorite subject.
the isolated flowers that endure, so impressive
you depict these beautifully
Thanks. You might be interested in pastPeter comment. He has a lot of interesting things to add to this about structural biology.
Wow!

Peter, thanks so much for sharing that!! Fascinating. There is a lot of beauty in structural biology.
