Perhaps you should try some spelling variations:
stationary sequences » binary sequences
linear sequences » line sequence, linear recurrences, integer sequences
sonar sequences » binary sequences, cover sequences, popper sequences

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

• If you are trying to use Boolean operators, they must be ALL CAPS: basic ((linear sequences) OR (((sonar sequences) OR (stationary sequences)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "basic ((linear sequences) or (((sonar sequences) OR (stationary sequences))))".
• Adding a wildcard symbol may retrieve word variants: basic ((linear sequences) or (((sonar sequences) OR (stationary sequences))))*.
