Query: Waldschmidt constants for Stanley-Reisner ideals of a class of
  Simplicial Complexes   We study the symbolic powers of the Stanley-Reisner ideal $I_{B_n}$ of a
bipyramid $B_n$ over a $n-$gon $Q_n$. Using a combinatorial approach, based on
analysis of subtrees in $Q_n$ we compute the Waldschmidt constant of $I_{B_n}$.
