Has an Olympic Basketball (Men) game ever ended 116-55?
Exactly once. On July 28, 1996, Lithuania beat China 116-55, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 116-55 in league history.
That makes 116-55 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 117-55 has happened never and 116-56 has happened never.
