Query: Classification of degenerations and Picard lattices of Kahlerian K3
  surfaces with the symplectic automorphism group (C_2)^2   Var3: In our papers 2013--2018 we classified degenerations and Picard
lattices of Kahlerian K3 surfaces with finite symplectic automorphism groups of
high order. For remaining groups of small order: $D_6$, $C_4$, $(C_2)^2$,
$C_3$, $C_2$ and $C_1$ it was not completely considered. Cases of $D_6$ and
$C_4$ were recently completely considered in [19] and [20]. Here we consider
the analogous complete classification for the group $(C_2)^2$ of the order 4.
