a Control parameters of the network topology of the tetra gel. The connectivity p increases monotonically with time and (ideally) reaches p = 2q after completion of the reaction, where q is the molar mixing fraction of the precursors of the minor group. b Dynamic process (DP) of gelation, where two precursors are mixed in a stoichiometrically balanced ratio (q = 1/2). c Static replicas (SR) of DP, where two precursors are mixed in a stoichiometrically imbalanced (and balanced) ratio (0 ≤ q ≤ 1/2). Here, the connectivity p after completion of the reaction is tuned as p = 2q
