'Pent-up' Frustration 2

November 2022 : Solution

For the November challenge you were asked to arrange 17 unit pentagons into a polypent to minimize the distance between two of the non-touching pentagons. A careful search gives several arrangements (one pictured above) with pentagons only ~0.1387573… apart. One exact form for this distance is sqrt(65/8 - (29 * sqrt(5))/8).

Congrats to this month’s solvers!
