Algebraic topology, an Uncommon card
Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces.

Power 104 (ATK + DEF): stronger than 45 % of WikiCards cards.
Algebraic topology quiz: 3 questions
Three questions on the Algebraic topology card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Algebraic topology, for example, allows for a ______ proof that any subgroup of a free group is again a free group.
Answer
convenient. Algebraic topology, for example, allows for a convenient proof that any subgroup of a free group is again a free group. From the Algebraic topology article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Volt. Volt 150,000 · Subset 97,000 · Algebraic topology 60,000 · Clock face 39,000 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 basic goal is to find algebraic invariants that classify topological spaces up to homeomorphism, though usually most classify up to homotopy equivalence.
- Although algebraic topology primarily uses algebra to study topological problems, using topology to solve algebraic problems is sometimes also possible.
- Algebraic topology, for example, allows for a convenient proof that any subgroup of a free group is again a free group.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Algebraic topology article was read about 60,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 64 and blocks with 40: each hit it takes is cut by 16 %.
How to get Algebraic topology
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.
