Phinary Drawers

This CAD model was designed by Oskar van Deventer, copyright (c), 27 August 2024.

Phinary Drawers is one of the results of a quest to design a "phinary" puzzle. That is, a puzzle where the number of moves removes increases exponentially with the number of pieces, but where the base is not an integer (2: binary; 3: ternary), but phi, the golden ratio (https://en.wikipedia.org/wiki/Golden_ratio, 1.618033988749..). Bram Cohen suggested this minor modification of his Binary Drawers puzzle. Iwahiro (Hirokazu Iwasawa) and Goetz Schwadner proved that this design is indeed phinary.
