All chain elements have some base element. Said base element must have a special property, which is that it cannot be defined as a chain element of something. The base element mixed with itself is a chain element of said base element. Also, a chain element of X + X, or a chain element of X + a chain element of X all turn into a chain element of X, where X is defined as some element, but all mentions of X are the same element.

A chain element is defined as a main chain element of X if it can be defined as some base element (x) mixed with itself, then that mixed with itself, and so on. This ignores the rule that the base element cannot be defined as a chain element of X.

A true main chain element is the same as a main chain element, but it does follow the rule that the base element is not a chain element of something.
