Abstract
The family of graphs $I_n$ will be introduced as approximation of network $T$ . It means that they are bipartite grahs with the set of points and lines isomorphic to $[0,1)^n$, $n>1$ such rhat their projective limit is well defined and coincides with $I.$ We prove that $I_n$ is a family of small world graphs of large girth. It means that the girth and diamrter of $I_n$ are linear expressions in variable $n$ We consider application of $I$ to secure transition of nondeterministic real strings of pseudorandom sequences of numbers of interval $[0,1)$.Graph $I$ satisfies to the definition of time-like graph [1]. So path in the graph can be an instrument for the time measurement of correspondent Markovian process. References, [1] .K.
