If you are interested about the spanish categories, third division, known as Segunda B is the gap between Pro and semi-pro football out of 4 categories which are , Tercera, Segunda B, Segunda and Primera. Primera being the top has 20 teams, Segunda 22 but Segunda B has this season 102 divided in 5 groups with Tercera being even more huge with one league pear each Spanish region. Thankfully this is due to change next season by removing 3º and 2ºB and adding 3 new categories with less teams making the fight for promotion a more sufferable hell but hopefully my dear Depor doesn't have to experience it and we win promotion this season.
