Lie algebra, an Uncommon card
In mathematics, a Lie algebra is a vector space g together with an operation called the Lie bracket, an alternating bilinear map g × g → g, that satisfies the Jacobi identity.

Lie algebra quiz: 3 questions
Three questions on the Lie algebra card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The Lie bracket of two ______ x and y is denoted [ x, y ].
Answer
vectors. The Lie bracket of two vectors x and y is denoted [ x, y ]. From the Lie algebra article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Lie algebra. Lie algebra 79 · Analog-to-digital converter 76 · Least squares 73 · Hyperbolic functions 70 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Hyperbolic functions. Hyperbolic functions 390,000 · Binomial coefficient 230,000 · Least squares 180,000 · Lie algebra 130,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- In other words, a Lie algebra is an algebra over a field for which the multiplication operation is alternating and satisfies the Jacobi identity.
- The Lie bracket of two vectors x and y is denoted [ x, y ].
- A Lie algebra is typically a non-associative algebra.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Lie algebra article was read about 130,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 79 and blocks with 59: each hit it takes is cut by 24 %.
How to get Lie algebra
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
