Stella u svome snu vidi različito numeriranih ovaca (od do ) i planira ih pojesti.
Stella je dosta neodlučna kod izbora ovaca koje misli staviti na ražanj, no ipak je odlučila da će za svake dvije ovce numerirane s i u skupu ovaca koje će pojesti (nazovimo taj skup ) vrijediti ova dva pravila:
- postoji ovca iz skupa čiji je broj takva da je relativno prost s i
- postoji ovca iz skupa čiji broj () nije relativno prost s i
Koliko će maksimalno ovaca Stella pojesti?

In her dream, Stella sees distinctly numbered sheep (from to ) and plans to eat them.
Stella is quite indecisive about the choice of sheep she wants to put on the spit, but she still decided that for every two sheep numbered and in the set of sheep she will eat (let's call that set ) these two rules will apply :
- there is a sheep from the set whose number is such that is relatively prime with and
- there is a sheep from the set whose number () is not relatively prime with and
How many sheep will Stella eat at most?
