No; most don't. The
Wikipedia entry for design patterns has the classifications and a list of the patterns in each.
I'm not sure what's giving you issues with regards to the definitions:
Creational: patterns related to object creation.
Structural: patterns related to the relationships between objects.
Behavioral: patterns related to the communication between objects.
Those are paraphrased from the Wikipedia entries for each of those classifications: what specifically don't you understand?
