Theorem ushgrun 16341
Description: The union  U of two (undirected) simple hypergraphs  G and  H with the same vertex set 
V is a (not necessarily simple) hypergraph with the vertex set  V and the union  ( E  u.  F
) of the (indexed) edges. (Contributed by AV, 29-Nov-2020.) (Revised by AV, 24-Oct-2021.)
