👉 Sodalities are a type of mathematical concept in which a number is divided by 2 to get a remainder of 1. For example, if you divide 48 by 2, you get 24, and then you take the second number (2), divide it by 2 again, and you get 12. The result of this division will be a divisor that is not divisible by 2, which is why we call it a sodality.
