| Abstract | We consider nine natural tightness conditions for topological spaces that are all variations on countable tightness, some stronger and some weaker than countable tightness. We investigate the interrelationships between them, presenting examples which show that mostly they are all different. However, a couple of intriguing problems of this type remain open. |
