"It's hard to define, but I know it when I see it" Supreme Court Justice Potter Stewart
At least two people
Loyalty to group
"A group is two or more people who for longer than a few moments, interact with and influence one another and perceive one another as 'us'"
"A collection of at least two people who are doing or being something together"
Roy Baumeister & Brad Bushman
"Groups have unique, emergent properties that differentiate them from a mere aggregate of individuals on three counts: perceived entitativity, perceived volition, and actual behavior"
" A group is a typically on-going interaction of multiple, often similar, people who are interdependent and for whom group identification is important"
H. Colleen Sinclair
