Perhaps you should try some spelling variations:
presentation » presentacion, presentado, presenteation, presentaation
presented » presente, presenta, presenteed, presentaed
presenteaan » presentedans, presenten, presentaban, presenteraan, presentean, presentaan, presenteeaan, presentaeaan
presentan » presenta, presente, presentacion, presentean, presentaan
presentea » presentera, presente, presenta, presenteea, presentaea
present » presente, presenta

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

• Performing a fuzzy search may retrieve terms with similar spellings: (presentation or ((presented or (presenteaan OR presentan)) or (presentea or present)))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presentation OR ((presented OR (presenteaan OR presentan)) OR (presentea OR present))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentation or ((presented or (presenteaan OR presentan)) or (presentea or present)))".
• Adding a wildcard symbol may retrieve word variants: (presentation or ((presented or (presenteaan OR presentan)) or (presentea or present)))*.
