Cardinality

Cardinality is a team that primarily participates in MIT Mystery Hunts. The team is based around the San Francisco Bay Area and has a prominent contingent from Stanford University. The team was started in 2020, and has placed top 10 in two Mystery Hunts since.

A subset of Cardinality runs the annual hunt Huntinality, which started in 2021.

History[edit | edit source]

Cardinality was founded in 2010 by a group of Stanford undergraduates, participating together in local hunts like DASH and Palantir. The team soon grew and included people from the general Bay Area. The team takes its name from the Stanford Cardinals and Cardinality from mathematics. Since its inception, the team has been quickly growing in numbers and improving in placements throughout hunts. Starting in 2020, Cardinality hunted as its own team in the MIT Mystery Hunt, having previously hunted with ✈✈✈ Galactic Trendsetters ✈✈✈ and Palindrome in the past.

Other team names used by Cardinality include Positive Mental Attitude / PMA, Five Guys, and Team Benji.[1]
