A covering is a combinatorial design: this set of tickets guarantees t hits from some 6 under stated conditions. A guarantee is not “the prize beats the cost.” Full Korean 6/45 is C(45,6)=8,145,060. Tightening the net buys more tickets and more cost. lottery-syndicate-odds is pooling. This essay is design vocabulary only. We do not sell a lock.
“Guarantee 3” is a conditional match count, not a first-prize lock.
Buying more tickets can enlarge the absolute EV (usually more negative). See lottery-expected-value.
Order versus combination is combination-vs-permutation-lotto.
If software says “mathematical lock,” walk away.
