The flag of South Korea, also known as the Taegukgi, has three parts: a white rectangular background, a red and blue Taegeuk in its center, and four black trigrams one toward each corner. Flags similar to the current Taegeukgi were used as the national flag of Korea by the Joseon dynasty, the Korean Empire, and the Korean government-in-exile during Japanese rule. South Korea adopted the Taegukgi as its national flag when it gained independence from Japan on 15 August 1948.

IATA codes are abbreviations that the International Air Transport Association (IATA) publishes to facilitate air travel. They are typically 1, 2, 3, or 4 character combinations that uniquely identify locations, equipment, companies, and times to standardize international flight operations.

In the fields of computational linguistics and probability, an n-gram is a contiguous sequence of n items from a given sample of text or speech. The items can be phonemes, syllables, letters, words or base pairs according to the application. The n-grams typically are collected from a text or speech corpus. When the items are words, n-grams may also be called shingles.
The trifid cipher is a classical cipher invented by Félix Delastelle and described in 1902. Extending the principles of Delastelle's earlier bifid cipher, it combines the techniques of fractionation and transposition to achieve a certain amount of confusion and diffusion: each letter of the ciphertext depends on three letters of the plaintext and up to three letters of the key.

The Bagua, Pakua or Palgwae are eight symbols used in Taoist cosmology to represent the fundamental principles of reality, seen as a range of eight interrelated concepts. Each consists of three lines, each line either "broken" or "unbroken", respectively representing yin or yang, 0 or 1 forming binary numbers 000-111.

Wen Wang Gua is a method of interpreting the results of I Ching divination that was first described in writing by Jing Fang in Han dynasty China. It is based on correlating trigrams to the Celestial Stems and Earthly Branches of the Chinese calendar, and then using the stem and branch elements to interpret the lines of the trigrams and hexagrams of the I Ching. The method is popular in South East Asia. It is known by various names: refers to the fact that it interprets the meaning of six symbols; the Najia method, indicates its logic of elemental values derived from the Chinese calendar; Wu Xing Yi ; or Wen Wang Ke.
Baguadao or Eight Trigram Teaching (八卦教) is a network of Chinese folk religious sects, one of the most extended in northern China.

Affiliated sects appeared under various names, but during the latter half of the 18th century they adopted Bagua Jiao as their common designation.
