Move the pink points. Play with slliders.
Here you see a giant configuration with 120 points and 120 lines such that
each line passes through 6 points and each point is incident to 6 lines.
The construction is based on a Poncelet polygon and fully movable. Play with the pink points
to explore the movability.
The construction is closely related to Desargues $(10_3)$-configuration.
It consists of 10 rings of points and 10 rings of lines each consisting of 12 objects.
There are various ways to consider the configuration composed from 12 rotated copies of a single Desargues configuration. Play with the sliders to explore the various ways Desargues configuration can be found in this $(120_6)$-configuration.
