Query: Detection of Large Scale Structure in a $B < 17^{m}$ Galaxy Redshift
  Survey   We report on results from the Durham/UKST Galaxy Redshift Survey where we
have found large scale ``cellular'' features in the galaxy distribution. These
have spatial 2-point correlation function power significantly in excess of the
predictions of the standard cold dark matter cosmological model$^{1}$,
supporting the previous observational results from the APM survey$^{2,3}$. At
smaller scales, the 1-D pairwise galaxy velocity dispersion is measured to be
$\bf 387^{+96}_{-62}$ kms$^{-1}$ which is also inconsistent with the prediction
of the standard cold dark matter model$^{1}$. Finally, the survey has produced
the most significant detection yet of large scale redshift space distortions
due to dynamical infall of galaxies$^{4}$. An estimate of $\bf \Omega^{0.6}/b =
0.55 \pm 0.12$ is obtained which is consistent either with a low density
Universe or a critical density Universe where galaxies are biased tracers of
the mass.
