removeEdges -- creates a list of graphs obtained by removing one edge from the given graph in all possible ways

• Usage:

  R' = removeEdges L

  R = removeEdges S

  R = removeEdges G

• Inputs:
  • L, a list, containing graphs in various formats
  • S, a string, a graph encoded in either Sparse6 or Graph6 format
  • G, a graph,
• Optional inputs:
  • MinDegree => an integer, default value null, the minimum degree which a returned graph can have
• Outputs:
  • R', a list, a list of all graphs obtained by removed one edge from the given graphs; it contains graphs in Graph6 or Sparse6 format
  • R, a list, a list of all graphs obtained by removed one edge from the given graph; it contains graphs in the same format as the input
