%N Smallest odd positive integer t such that the prefix of length tn of the Thue-Morse sequence (A010060) is an n-antipower.
%C A word of length tn is an n-antipower if all n consecutive blocks of length t are distinct.

%e For n = 3, the prefixes (0)(1)(1) and (011)(010)(011) are not 3-antipowers, but the prefix (01101)(00110)(01011) is.
