part of grupo rio, what is now known as access group b would only come to be in 1960, at the time known as group 3 - laying the grounds for what is generally referred to as the third division of the carioca carnival.

the definition of divisions actually helps to better understand the championship among its sporadic changes in designations - samba schools in the group b are the best among the teams in groupo rio, as they are only one victory away from joining the groupo de acesso and parading in the sambódromo.

Schools parading in this group are required to have 3 allegories, 18 wings, and an orquestra, among other things.
