Abstract
The model consisting of gravitational, scalar and axionic fields is considered. It is shown that the action of the Lavrelashvili-Rubakov-Tinyakov wormhole can be made arbitrarily negative by varying the parameters of the model. This means that semiclassically calculated probability of transition through this wormhole is not exponentially small (as usual) but exponentially large.
