When dimensional locations are given as ordered lists of numbers such as (t,x,y,z) they are called vectors or n-tuples. It is only when such locations are linked together into more complicated shapes that the full richness and geometric complexity of 4D and higher spaces emerges. A hint of that complexity can be seen in the accompanying animation of one of simplest possible 4D objects, the 4D cube or tesseract.

Since the 1960s, South Korea has emerged as a major football power in Asia and is historically the most successful Asian football team, having participated in nine consecutive and ten overall FIFA World Cup tournaments, the most for any Asian country. Despite initially going through five World Cup tournaments without winning a match, South Korea became the first and currently only Asian team to reach the semi-final stages when they co-hosted the 2002 tournament with Japan. They have since improved their ability to play on foreign soil and were able to reach the Round of 16 in the 2010 World Cup. South Korea won the first two AFC Asian Cup tournaments though they have been unable to win since, finishing second in 1972, 1980, 1988, and 2015, and third in 1964, 2000, 2007, and 2011. They also took the gold medal at the 1970, 1978, and 1986 Asian Games. They have qualified for every FIFA World Cup since 1986.
