  Hi Marius,

  you can run presolve through

  p = m.presolve()

  and then print the statistics of this new model through

  p.printStats()

  which will show you the statistics about the model

  You can find more information about presolve here: https://support.gurobi.com/hc/en-us/articles/360024738352-How-does-presolve-work-
