+# What is Amicable Chains?
+# Amicable chains are a sequence of numbers in which each number is the sum of the proper divisors of the number that follows it. For example, consider the sequence 220, 284, 220, 284, ... Here, 220 is the sum of the proper divisors of 284, and 284 is the sum of the proper divisors of 220.
