Poliedri di Johnson

Ennio Bolzonella, 22/05/2019

Un solido di Johnson è un poliedro convesso le cui facce sono poligoni regolari. Questa definizione è molto generica ed include anche i solidi platonici, quelli archimedei, i prismi e gli antiprismi. Togliendo dalla definizione generale le categorie citate rimangono 92 poliedri, questi sono i solidi di Johnson propriamente detti. Questo libro ne rappresenterà alcuni.
