max_list/2	True if Max is the largest number in List.
max_member/2	True when Max is the largest member in the standard order of terms.
max_member/3	True when Max is the largest member according to Pred, which must be a 2-argument callable that behaves like (@=<)/2.
member/2	True if Elem is a member of List.
min_list/2	True if Min is the smallest number in List.
min_member/2	True when Min is the smallest member in the standard order of terms.
min_member/3	True when Min is the smallest member according to Pred, which must be a 2-argument callable that behaves like (@=<)/2.
nextto/3	True if Y directly follows X in List.
nth0/3	True when Elem is the Index'th element of List.
nth0/4	Select/insert element at index.
nth1/3	Is true when Elem is the Index'th element of List.
nth1/4	As nth0/4, but counting starts at 1.
numlist/3	List is a list [Low, Low+1, ... High].
permutation/2	True when Xs is a permutation of Ys.
prefix/2	True iff Part is a leading substring of Whole.
proper_length/2	True when Length is the number of elements in the proper list List.
reverse/2	Is true when the elements of List2 are in reverse order compared to List1.
same_length/2	Is true when List1 and List2 are lists with the same number of elements.
select/3	Is true when List1, with Elem removed, results in List2.
select/4	Select from two lists at the same position.
selectchk/3	Semi-deterministic removal of first element in List that unifies with Elem.
selectchk/4	Semi-deterministic version of select/4.
subseq/3	Is true when SubList contains a subset of the elements of List in the same order and Complement contains all elements of List not in SubList, also in the order they appear in List.
subset/2	True if all elements of SubSet belong to Set as well.
subtract/3	Delete all elements in Delete from Set.
sum_list/2	Sum is the result of adding all numbers in List.
union/3	True if Set3 unifies with the union of the lists Set1 and Set2.
