The task is defined by example.

Let's try to formalize it:

all valid matches contain only characters from the set [123abcdefghi.];

significance of 3 characters separated by dot is questionable because one valid example has 4 characters in a row. Let's assume we can have arbitrary number of characters separated by dots.

It is unclear if we can use any letter from the valid range in any group; let's assume that all groups are equivalent

then, repeated group will be [123abcdefghi\.]+

Add start and end anchors to match complete lines only:

r='^[123abcdefghi.]+$'

this is one of many possible understandings of this set of examples.
