It's impossible to purchase all 175 million combinations.
Imagine if you could have a ticket printed every 10 seconds. That's 1.75 BILLION seconds it would take.
1.75 billion seconds is 29,166,167 minutes = 486,111 hours.
SO if you employed 10,000 who could purchase the ticket combos that would take 48 hours non-stop.
That's just to receive the printed tickets.
How long do you think that it would take 10,000 employees to type in all of the printed combos AND receive the printed tickets? It would take forever, son. Forever.
