It’s an ad-hoc system. Don’t try to look for a hidden beautiful logic. The “system” only makes sense to employees who’ve learned the numbers by heart. It’s trying and failing at keeping track of all the possible manufacturing processes, their related constraints (some elements only come in sets of different bricks, other come only in a minimum quantity). Also the nomenclature in house is a mess: terms like bricks, elements and parts are used interchangeably depending on the department. Source: I worked at LEGO.
