Let \(P_w(n)\) be the set of distinct subwords (intervals) in a word \(w\).
Let \(p_w(n)\) be the cardinality of \(P_w(n)\).
Let \(f(c)\) be the sequence in FASTA with 4-symbol Protein Data Bank code \(c\).
\(|P_{f(4ZVN_1)}(2) \setminus P_{f(4UZX_1)}(2)|=134\),
\(|P_{f(4UZX_1)}(2) \setminus P_{f(4ZVN_1)}(2)|=22\).
Let
\(
Z_k(x,y)=|P_x(k)\setminus P_y(k)|+|P_y(k)\setminus P_x(k)|
\)
be a LZ76 style (set of subwords) Jaccard distance numerator for \(P(k)\).Hydrophobic-polar version of Sequence 1:11001111010001001010100111001000100101001011010101000010101001011001100001000001100100000010010111101110110111110111001100111101111000111010111101001101010000110100001111100101010110111101011101100000011111100010011000111001010110

Let d be the

distance d.
Let d1 be the Otu--Sayood distance d1. (This makes the 4TYN sequence AAAAAA a close match...)

In notation analogous to
[Theorem 16, Kjos-Hanssen, Niraula and Yoon (2022)],
\[
\delta=

\begin{cases}
d &\alpha=0,\\
d_1/2 &\alpha=1/2
