gives the number of sublists in list that match the general sequence pattern patt.
Details and Options
- In SequenceCount[list,patt], patt can be an expression with head List that includes pattern constructs such as PatternSequence, Repeated (..), Blank (_), and BlankSequence (__).
- The pattern patt can also be a pattern that matches a list, though does not itself have head List.
- With the default option setting OverlapsFalse, SequenceCount includes only sublists that do not overlap. With the setting OverlapsTrue, it includes sublists that overlap.
- With Overlaps->All, multiple sublists that match the same pattern are all included. With Overlaps->True, only the first such matching sublist at a given position is included.
