Comment (by dimpase):
The cross-intersection of two
such partitions `P=\{P_1,P_2,P_3\}` and `P'=\{P'_1,P'_2,P'_3\}`
being
defined as `\{P_i\cap P_j: 1\leq i,j\leq 3\}`,
there is something strange in this definition: the 2nd part does not use
`P'` at all.
Also, a space before `\cap` will make it more readable online.
