It is easy to see that a yes instance of GRAPH MOTIF on this graph is equivalent to a solution to the original 3SAT

A related, but more complex, argument shows that such reasoning is, in fact NP-hard: here we can encode an arbitrary 3SAT
problem by including a node that represents the boolean formula, connected to nodes that represent the clauses (with a CPtable that insures that the formula is true iff all of the clauses is true), and the clause-nodes are each connected to nodes that represent the boolean variables (with CPtable that insure that the clause node is true iff the associated boolean variables have the correct setting).
The complete sets used here are primarily 3SAT
(is this Boolean formula in 3-CNF form satisfiable) and succinct SAT (the formula is again given by a circuit).

To simplify the presentation we consider the most popular setting--the case k = 3, namely random 3SAT
, and remark that our results extend to any fixed k.
