216 is the smallest untouchable number which is also a cube
Plato's number: Plato alludes to the fact that 216 is equal to 63, where 6 is one of the numbers representing marriage since it is the product of the female 2 and the male 3. Plato was also aware of the fact the the sum of the cubes of the 3-4-5 Pythagorean triple is equal to 216
Two hundred sixteen 216 = 23*33 = 63 = 33 + 43 + 53, making it the smallest cube that's also the sum of three cubes
