heal.abstract	We perform Monte Carlo simulations of a four-dimensional gauge-invariant spin system which describes random surfaces with gonihedric action. We develop the analogy between the flat-crumpled phase transition of the lattice surface model and the liquid-gas phase transition of non-ideal gases, and identify the self-intersection coupling constant Ic of the surface model with the pressure P. As k increases the system moves to a critical point in complete analogy with the situation for non-ideal gases, where the liquid and the gas phases approach each other with increasing P. We measure vacuum expectation values of various operators and the corresponding critical indices.	en
