Fixed Digits Repetitions Prime Patterns of Length 7

Inder J. Taneja

The author in 2017, worked with patterns in prime numbers in such a way that they can be extended by inserting digits in repeated ways, and still remains  prime numbers. These types of prime numbers are called fixed digits repetitions prime patterns . In this work, multiple choice prime patterns are considered.  Multiple choice means that the same pattern can be represented by more than one way. The work is for prime patterns of length 7. When we talk of length 7, it means that the pattern at length 8 is no more a prime number. A complete list of primes patterns with possible number of digits repetitions is written in reduced form. This work is revised and enlarged version of author's previous two works done in 2017. The revised and enlarge version of work on lengths 10, 9 and 8 can be seen in [14].
