Bob, use

tmp=Split[{1,1,2,2,2,-1,0,3,3,3,5}];

occur = Length/@tmp;

now, Max[occur] will give you the count, while

tmp[[ Flatten[Position[ occur, Max[ occur ] ] ] ]]


will give you the actual list(s)

Mathematica had many programmed functions which are not referenced in the
help index. Under '?Position -> Further Examples' you will find two such
functions, 'ConsecutiveOccurrences1' and 'ConsecutiveOccurrences2.' I
first wish that Mathematica would index these.

But the reason for writing is that I have a need for a function named
'MaxConsecutiveOccurrence' which would return the maximum consecutive
occurrence of x in a list.

Thank you in advance.


Bob.
