# Parties

# Text

This is a public pledge known as "Extremely

Young". Any person CAN join this contract by announcement if and only

if the 2-adic absolute value of eir age (in years, rounded down) <=

0.25. Any party to this contract CAN leave this contract by

announcement. Parties to this contract are known as Designees.

# Explanation

From Wikipedia:

For a given prime p, we define the p-adic absolute value in Q as follows: for any non-zero rational number x, there is a unique integer n allowing us to write x = p

^{n}(a/b), where neither of the integers a and b is divisible by p. Unless the numerator or denominator of x in lowest terms contains p as a factor, n will be 0. Now define |x|_{p}= p^{−n}. We also define |0|_{p}= 0.

Thus, a person CAN join if and only if eir age is an integral multiple of 4.
