Connecting computers and printers (combinatorics)

[majkvel]

There are 15 computers and 10 printers in the computer room. Ten computers need a printer every 5 minutes, and only one computer can use the printer at a time. Make sure that at least 6 computers must be connected to each printer. Therefore, the minimum number of links required for each computer to have the printer available whenever it needs it is 60. Design a scheme with 60 links that suits your task.
