Query: Analysis of the Superkamiokande atmospheric neutrino data in the
  framework of four neutrino mixings   Superkamiokande atmospheric neutrino data for 990 days are analyzed in the
framework of four neutrinos without imposing constraints of Big Bang
Nucleosynthesis. It is shown that the wide range of the oscillation parameters
is allowed at 90% confidence level ($0.1\lsim |U_{s1}|^2+|U_{s2}|^2\le 1$).
