5 Conclusions and summary

We obtained 117 new redshift measurements of GCGC galaxies, 102 of which in the direction of the Coma-A 1367 supercluster. With the new data, the total number of available redshifts in this direction of the sky is 1068 ($m_{\rm p}\le 15.7$).

The supercluster is centered at $\sim\!\! 7200$ $\rm km\,s^{-1}$ and it extends from 6000 to 8500 $\rm km\,s^{-1}\!$.It contains two rich clusters (Coma + A 1367) whose "fingers of God" stretch from 4000 to 10000 $\rm km\,s^{-1}\!$.

By computing of the local galaxy density around each object, we separate galaxies belonging to five groups, from several multiplets and relatively isolated objects within the supercluster. This classification will be used to study the environmental dependence of properties of galaxies spanning over an order of magnitude in local density.
