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 \(c\).
\(|P_{f(7WQM_1)}(2) \setminus P_{f(5KZQ_1)}(2)|=60\),
\(|P_{f(5KZQ_1)}(2) \setminus P_{f(7WQM_1)}(2)|=111\).
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 1:10000000000001010010111111110011101100011010011101110010010100000011111000110101000011000011001001011011100010010100101011001101011001010000101110110100010110000011110011100100001011100111000110001000101000011010000011111001110000001101001111001110111000000111111000100111111000000010001011010101001011011000100100001100100100000
Let d be the
Otu--Sayood
distance d.
Let d1 be the Otu--Sayood distance d1. (This makes the 4TYN sequence AAAAAA a close match...)
A roughly speaking expected distance is \((0.85)(0.8)(\frac{899
}{\log_{20}
899}-\frac{329}{\log_{20}329})=153.\)

In notation analogous to
[Theorem 16, Kjos-Hanssen, Niraula and Yoon (2022)],
\[
\delta=
\alpha \mathrm{min} + (1-\alpha) \mathrm{max}=
\begin{cases}
d &\alpha=0,\\
d_1/2 &\alpha=1/2
\end{cases}
