For p=n−2/3logn, the expected number of pairs of K4​ copies sharing a vertex is
O(n7p12+n6p11+n5p9)=o(1).
(1)
Thus, with probability tending to one, all the K4​ copies are vertex-disjoint. Together with sparse clique-count concentration, this gives arbitrarily many vertex-disjoint copies with probability tending to one.
