de bases » de base, de gases, de bayes
marcos y » marcas y, barcos y, marco y
de 1920 » de 1930, de 1980, de 1990

bases a » bases y, base a, bases _
a 1860 » la 1860, a 1850, a 1820

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierta de 1920 de bases a 1860 ) OR ( Cabildo abierto al 23 _ marcos y 1930 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 1920 de bases a 1860 ) OR ( Cabildo abierto al 23 _ marcos y 1930 ))*.
