It's not allower, the sizes aren't identical. Sean.

Then I think you can perfectly use the function below: bool bitset_vector_less( const std::vector< std::bitset< 6 > > & lhs, const std::vector< std::bitset< 6 > > & rhs ) { assert( lhs.size() == rhs.size() ); return std::equal( lhs.begin(), lhs.end(), rhs.begin(), BitSetComp() ); } where BitSetComp is the predicate you have shown earlier.
