Bravais lattice, an Uncommon card
In geometry and crystallography, a Bravais lattice, named after Auguste Bravais, is an infinite array of discrete points generated by a set of discrete translation operations, where the lattice is exactly the same from each of the discrete lattice points.

Bravais lattice quiz: 3 questions
Three questions on the Bravais lattice card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The choice of ______ vectors for a given Bravais lattice is not unique.
Answer
primitive. The choice of primitive vectors for a given Bravais lattice is not unique. From the Bravais lattice article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Internal energy. Internal energy 71 · Human skeleton 66 · Bravais lattice 63 · Adenine 59 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Human skeleton. Human skeleton 170,000 · Electric potential 130,000 · Explosion 95,000 · Bravais lattice 73,000 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.
- The set of translation operations is described in three dimensional space by R = n 1 a 1 + n 2 a 2 + n 3 a 3, where the ni are any integers, and ai are primitive translation vectors, or primitive vectors, which lie in different directions and span the lattice.
- The choice of primitive vectors for a given Bravais lattice is not unique.
- The Bravais lattice concept is used to formally define a crystalline arrangement and its frontiers.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Bravais lattice article was read about 73,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 49: each hit it takes is cut by 20 %.
How to get Bravais lattice
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.
