%N A332279 Number of widely totally normal compositions of n.
%C A332279 A sequence is widely totally normal if either it is all 1's (wide) or it covers an initial interval of positive integers (normal) and has widely totally normal run-lengths.
%C A332279 A composition of n is a finite sequence of positive integers with sum n.
%F A332279 For n > 1, a(n) = A332296(n) - 1.
%e A332279 The a(1) = 1 through a(7) = 22 compositions:
%e A332279 (1) (11) (12) (112) (122) (123) (1123)
%e A332279 (21) (121) (212) (132) (1132)

%e A332279 For example, starting with y = (3,2,1,1,2,2,2,1,2,1,1,1,1) and repeatedly taking run-lengths gives y -> (1,1,2,3,1,1,4) -> (2,1,1,2,1) -> (1,2,1,1) -> (1,1,2) -> (2,1) -> (1,1). These are all normal and the last is all 1's, so y is counted under a(20).

%Y A332279 Normal compositions are A107429.
%Y A332279 Constantly recursively normal partitions are A332272.
%Y A332279 The case of partitions is A332277.
%Y A332279 The case of reversed partitions is (also) A332277.
%Y A332279 The narrow version is A332296.
%Y A332279 The strong version is A332337.
%Y A332279 The co-strong version is (also) A332337.
