    simple 3 bar chain with no link fixed......
    that will give you- 3(3)-2x3=3
    since no link is fixed we wont subtract 1 from three

    3 links do not form a kinematic chain.

    they form an open chain, or if the chain is closed, it results in a superstructure

    that is impossible with just three links

    3 links cannot form a kinematic chain.

    either an open chain or a rigid chain can be formed.
