72
Nine times eight
Seventy-two, the number between 71 and 73.
In casual speech, 72 often serves as shorthand for a standard comfortable temperature in Fahrenheit: Set the thermostat to 72.
The number appears in religious and mystical contexts—72 names of God, 72 virgins—and in the Rule of 72, a formula for estimating how long an investment takes to double.
