    "abstract": "An idealised experiment estimating the spacetime topology is considered in\nboth classical and quantum frameworks. The latter is described in terms of\nhistories approach to quantum theory. A procedure creating combinatorial models\nof topology is suggested. The correspondence between these models and\ndiscretised spacetime models is established.",
