This is a 4 sphere Venn diagram, representing a 4-ary Boolean function.

The spheres stand for sets or statements A, B, C, D.

Examples:

${\displaystyle A\cap B}$	${\displaystyle \cap }$	${\displaystyle C~}$	${\displaystyle =~}$	${\displaystyle A\cap B\cap C}$
	${\displaystyle \cap }$		${\displaystyle =~}$

${\displaystyle A\cap B\cap C}$	${\displaystyle \cap }$	${\displaystyle D~}$	${\displaystyle =~}$	${\displaystyle A\cap B\cap C\cap D}$
	${\displaystyle \cap }$		${\displaystyle =~}$

${\displaystyle \{\}^{C}~}$	${\displaystyle \setminus ~}$	${\displaystyle D~}$	${\displaystyle =~}$	${\displaystyle D^{C}~}$
	${\displaystyle \setminus ~}$		${\displaystyle =~}$
