█████ ████████

Em ███████████, ███████████████ em ██████ das ██████████████, o █████ ████████, ██████ ███████ █████████ ██████████ ou ███████████, de uma ████████ █████████ é a ████ do ███████ de ████ █████████████ de █████ da ███████████ pelo seu ██████████ █████. Isto é, ██████████ o █████ █████ "████████" de uma ███████████ se ela ███ ████████ ██████ █████. ████-se que o █████ em ██ pode ███ ser ████████ no ███████ █████; pode ser ██████████ ou ██████████. Se █████ os ███████ ███████ █████ █████████████ o █████ ████████ é a █████ ██████████.
