Groups of Prime Numbers'
Second Differences: 
Introduction of variations 
explains what is the reason to go to the
next, more profound, step in dynamic structure of primes 
Regular and repeating irregular
groups 
of consecutive
variations in the range
of primes until 1,000,000,000 
Maximal sizes of regular and
repeating irregular groups 
depend on dynamic characteristics
of each type of them 
Groups in the range
until 100,000 
statistics of repeating
groups
of consecutive variations 
Groups in the range
until 1,000,000 
statistics of repeating
and regular groups
of consecutive variations

Classes of Prime Numbers and Their
Differences: 
Key of primes 
is number 6 
Distributions of gaps and variations 
show six period oscillations 
Boolean algebra of classes 
of primes from 7, gaps, and
variations 
Consecutive primes 
can be of
any class independently in the infinite general primes' set 
Distribution of groups of primes of the same class in the
infinite general set 
in
consequence of appearing consecutive primes of any class
independently 
Distribution of groups of primes of the same class in the finite
range 
statistics and analysis differences from that in the infinite
general set
