  The problem of genealogy of permutations has been solved partially by Stefan
(odd order) and Acosta-Hum\'anez \& Bernhardt (power of two). It is well known
that Sharkovskii's theorem shows the relationship between the cardinal of the
set of periodic points of a continuous map, but simple permutations will show
the behaviour of those periodic points. Recently Abdulla et al studied the
structure of minimal $4n+2$-orbits of the continuous endomorphisms on the real
line. This paper studies some combinatorial dynamics structures of permutations
of mixed order $4n+2$, describing its genealogy, using Pasting and Reversing.
