In the “Share with group” checkbox, it allows any group members to move, modify, delete the object. (but they won't be able to take it or make a copy to own)

The “Allow anyone to copy” lets anyone to make a copy of the object (by going to the menu Edit:Duplicate). Once a copy is made, they can take the copy (into their inventory). They can repeat this process to obtain many copies.
In the “Next owner can:” section, note that one of “Copy” or “Resell/Give away” must be selected. (it is not possible to have both boxes unchecked.)
above: The “When Left-clicked:” menu content, allows you to set the default behavior for left-clicking the object.
