Noncontiguous Substrings and
Onetoone Finite Sequences

Summary.

This text is a continuation of [3]. We prove a number
of theorems concerning both notions introduced there and onetoone finite
sequences. We introduce a function that removes from a string elements of
the string that belongs to a given set.
The terminology and notation used in this paper have been
introduced in the following articles
