Number of people in a guild required to get guild-allstar points?

Could you clear this up for me? I thought at least 18 people needed to be in the same guild in the guild’s log for it to be valid for guild-allstar points. I think that it’s all been word of mouth up to this point, so a final word would be great! Thanks

20-man Mythic raid, 12 or more would be considered a guild kill” @Kihra
