comment The $5n+1$ Problem
It's not clear from the excerpt I quoted, but in that article the "size" of a cycle refers to the number of distinct odd elements in the cycle, not the length.

You may want to look into count-min sketches (essentially, the multi-set version of Bloom filters).

comment How many players needed for the game to have the highest probability of finishing the fastest?
What happens when a player is marked with multiple colors at once? What happens when $A\rightarrow C\wedge B\rightarrow C$?

comment How many players needed for the game to have the highest probability of finishing the fastest?
What about $A \rightarrow C \wedge B \rightarrow C$? And what actually is the result of $A \rightarrow B \wedge B \rightarrow A$?

comment Mapping a set of sets to a partitioning.
Is it clear that you've "partitioned $U$ into $2^n$ distinct sets"? What if your sets are such that there exist two elements $e_1$ and $e_2$ such that $e_1 \in S_i \iff e_2 \in S_i$ for all $i$?
