What is the difference between Cro-Magnons and Neanderthals culture?

Neandertals lived in small groups, consisting from 25 to 8 people in each group. These groups were widely separated, though it is possible that they interacted once in a while. These groups must have been clans or families. The Cro-Magnon social structure is vaster. They lived in a larger groups, with far more people in these groups than Neandertal groups. Therefore, these groups may have been tribes. And it is highly likely that they interacted with each other, more so than Neanderthals and the Cro-Magnon were more in reach with other tribes.
