What circuit does the samsung NE58H9970WS induction range need?
The documentation (PDF) says


  Use only a 3-conductor or a 4-conductor UL-listed range cord...


Range cords typically have NEMA 14-50 Plugs on the end, so you'll need a NEMA 14-50 receptacle to plug the range into.

The documentation also says.


  A range cord rated at 40 amps with 125/250 minimum volt range is required. A 50 amp range cord is not recommended but if used, it should be marked for use with nominal 1 3⁄8” diameter connection openings.


And that the range is rated at 8,750  -  16,500 watts, when connected to a 120/240 volt 3 wire circuit. National Electrical Code says that you'll need at least a 40 ampere breaker, and 8 AWG copper conductors and 10 AWG copper ground.

Here's some further reading explaining the actual code.
