- As it contrasts with a linear continuum, the Cantor set has been called the Cantor discontinuum.
- Through consideration of this set, Cantor and others helped lay the foundations of modern point-set topology.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cantor set article was read about 91,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 68: each hit it takes is cut by 27 %.
How to get Cantor set
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.
