A class of $2$-local finite spectra which admit a $v_2^1$-self-map
  At the prime $2$, Behrens, Hill, Hopkins and Mahowald showed $M_2(1,4)$ admits $32$-periodic $v_2$-self-map and more recently authors joint with Mahowald showed $A_1$ also admits $32$-periodic $v_2$-self-map. This leads to the question, whether there exists a finite $2$-local complex with periodicity less than $32$. This paper will answer the question by producing a class of finite $2$-local spectra $\widetilde{\mathcal{Z}}$ all of which admit $1$-periodic $v_2$-self-map.
