Connected space, an Uncommon card
In topology and related branches of mathematics, a connected space is a topological space that cannot be represented as the union of two or more disjoint non-empty open subsets.

Power 123 (ATK + DEF): stronger than 60 % of WikiCards cards.
Connected space quiz: 3 questions
Three questions on the Connected space card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Some related but stronger ______ are path connected, simply connected, and n -connected.
Answer
conditions. Some related but stronger conditions are path connected, simply connected, and n -connected. From the Connected space article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Palmitic acid. Palmitic acid 70,000 · Connected space 52,000 · Obesity hypoventilation syndrome 23,000 · Actaea 13,000 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.
- Connectedness is one of the principal topological properties that distinguish topological spaces.
- A subset of a topological space X is a connected set if it is a connected space when viewed as a subspace of X.
- Some related but stronger conditions are path connected, simply connected, and n -connected.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Connected space article was read about 52,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 53: each hit it takes is cut by 21 %.
How to get Connected space
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.
