Split

Split[list]
splits list into sublists consisting of runs of identical elements.

Split[list, test]
treats pairs of adjacent elements as identical whenever applying the function test to them yields True.

Split in increasing runs of elements:

Decreasing runs of elements:

Split based on first elements:

Split at jumps:

Split so that in each sublist successive elements are not the same:

Split after every occurrence of a:

Split before every occurrence of a:

Group together identical elements:

Run-length encoding:

Group equivalence classes according to an equivalence function:

Distribution of lengths of runs of 0s or 1s in the first million bits of

Distribution of lengths of runs of 0s or 1s in one million pseudorandom bits:

Flatten acts an inverse of Split:

Find runs of numbers in base 10 that contain the same number of 1s:
