| Jul 31, 2014 at 5:26 | comment | added | Max Suica | Thanks, guys! It turns out we can use $E = \{1,2,3\}$ and consider $\{a,b\}_1 \cap \{b,c\}_1 = \{\{a,c\}, \{a\}, \{b\}, \{c\}, \{\}\}$. Primitive $A_k$ sets that contain an element of cardinality 2 will either have more than one element of cardinality 2 (in the case where $|A| \geq 2$, $k \geq 2$), or they will lack one of the singleton elements (in the case where $|A| = 1$, $k=1$.) Nate - out of curiosity, what language did you use for the program? Was it simple to express the problem? | |
