The winning $201.9-million Powerball ticket was claimed Tuesday morning, a New York Lottery spokeswoman said.
"We are now coordinating a date, place and time to award the prize," lottery spokeswoman Carolyn Hapeman said in an email. She had no further information.
The holders of the ticket -- for the biggest lottery prize in Long Island history -- are reportedly a group of about 20 employees who work at the Costco store on Route 110 in Melville.
A day after the drawing last Wednesday night, employees said about 100 people work at the Melville Costco, about 20 of whom are in the "lottery club."
Workers have been tight-lipped about the winners.
The winning ticket was bought at the Maulik & Chandni stationery store on West Montauk Highway in Lindenhurst. The numbers were 8, 18, 38, 46 and 56, with the Powerball 31.
In New York, the seller of a winning Powerball ticket gets $10,000, a lottery spokeswoman said.
