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 \(c\).
\(|P_{f(8EGM_1)}(2) \setminus P_{f(7RSZ_1)}(2)|=67\),
\(|P_{f(7RSZ_1)}(2) \setminus P_{f(8EGM_1)}(2)|=98\).
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 1:1100000010010111111111011101110110010100101011000100111011110010010110111100110010101101100011111010111011000011111100100000011101111111010111110101110010111000111010000101101011111100101001100110100100011011001110111110100111001110110101001100010101101000110011011010001101010111100110011011110001100011101101101110
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 \((0.85)(0.8)(\frac{678
}{\log_{20}
678}-\frac{316}{\log_{20}316})=100.\)

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}
