The notion of the geometrical $\Z/2 \oplus \Z/2$--control of self-intersection of a skew-framed immersion and the notion of the $\Z/2 \oplus \Z/4$-structure (the cyclic structure) on the self-intersection manifold of a $\D_4$-framed immersion are introduced. It is shown that a skew-framed immersion $f:M^{ \frac{ 3n+q}{ 4}} \looparrowright \R^n$, $0 < q <<n$ (in the $\frac{ 3n}{ 4}+\epsilon$-range) admits a geometrical $\Z/2 \oplus \Z/2$--control if the characteristic class of the skew-framing of this immersion admits a retraction of the order $q$, i.e. there exists a mapping $\kappa_0: M^{ \frac{ 3n+q}{ 4}} \to \RP^{ \frac{ 3(n-q)}{ 4}}$, such that this composition $I \circ \kappa_0: M^{ \frac{ 3n+q}{ 4}} \to \RP^{ \frac{ 3(n-q)}{ 4}} \to \RP^{ \infty}$ is the characteristic class of the skew-framing of $f$. Using the notion of $\Z/2 \oplus \Z/2$-control we prove that for a sufficiently great $n$, $n=2^l-2$, an arbitrary immersed $\D_4$-framed manifold admits in the regular cobordism class (modulo odd torsion) an immersion with a $\Z/2 \oplus \Z/4$-structure. In the last section we present an approach toward the Kervaire Invariant One Problem.
