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 \(c\).
\(|P_{f(7QPP_1)}(2) \setminus P_{f(5KVY_1)}(2)|=99\),
\(|P_{f(5KVY_1)}(2) \setminus P_{f(7QPP_1)}(2)|=68\).
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 1:10010010101000000111111010000001000010010111010011101010100101110110110001001111101111100100000111100011011110000010100101001000000010010011001011011101011100101000001111110110100111001111011000100010001000011110011010110011010010000000000101010001010111101110010

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

\[
\delta=

\begin{cases}
d &\alpha=0,\\
