 * The $24$th Zuckerman number after $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$, $11$, $12$, $15$, $24$, $36$, $111$, $112$, $115$, $128$, $132$, $135$, $144$, $175$, $212$:
 * $216 = 18 \times 12 = 18 \times \left({2 \times 1 \times 6}\right)$


 * The $1$st element of the $2$nd set of $4$ positive integers which form an arithmetic progression which all have the same Euler $\phi$ value:
 * $\phi \left({216}\right) = \phi \left({222}\right) = \phi \left({228}\right) = \phi \left({234}\right) = 72$


 * The $7$th positive integer after $64$, $96$, $128$, $144$, $160$, $192$ with $6$ or more prime factors:
 * $216 = 2 \times 2 \times 2 \times 3 \times 3 \times 3$


 * The $12$th of the $17$ positive integers for which the value of the Euler $\phi$ function is $72$:
 * $73$, $91$, $95$, $111$, $117$, $135$, $146$, $148$, $152$, $182$, $190$, $216$, $222$, $228$, $234$, $252$, $270$


 * The $1$st cube which can be expressed as the sum of $3$ positive cubes:
 * $216 = 3^3 + 4^3 + 5^3$


 * The $42$nd positive integer $n$ such that no factorial of an integer can end with $n$ zeroes.
