theorem Th96:
for G being SimpleGraph, u being set
 st u in Vertices G holds { [u, union G], union G} in Mycielskian G
proof
  let G be SimpleGraph, u be set such that
A1: u in Vertices G;
   { [u, union G], union G} in Edges Mycielskian G by A1,Th90;
  hence { [u, union G], union G} in Mycielskian G;
end;
