29.6 UnionBlist

UnionBlist( blist1, blist2.. )
UnionBlist( list )

In the first form UnionBlist returns the union of the boolean lists blist1, blist2, etc., which must have equal length. The union is a new boolean list such that union[i] = blist1[i] or blist2[i] or ...

In the second form list must be a list of boolean lists blist1, blist2, etc., which must have equal length, and Union returns the union of those boolean list.

    gap> blist1 := [ true, true, false, false ];;
    gap> blist2 := [ true, false, true, false ];;
    gap> UnionBlist( blist1, blist2 );
    [ true, true, true, false ] 

Note that UnionBlist is implemented in terms of the procedure UniteBlist (see UniteBlist).
