Exercise: Look through the entire set of Johnson solids and determine which of them are chiral.

Answer: Surprisingly few of the 92 are chiral. Only these five:

• gyroelongated triangular bicupola (J44)
• gyroelongated square bicupola (J45)
• gyroelongated pentagonal bicupola (J46)
• gyroelongated pentagonal cupolarotunda (J47)
• gyroelongated pentagonal birotunda (J48)
