These are the three-digit numbers that can be read from the simultaneously visible faces that share the same corner on a 6-sided die with a traditional layout (in which the number of pips of opposite sides add up to 7).
3-digit numbers such that the digits are distinct and in 1..6, no two digits add up to 7. - Jianing Song, Mar 21 2021
