High-confidence facts extracted from structured source data. Use them as anchors for further research.

Alphabet size

2 {\displaystyle 2}

Block length

n {\displaystyle n}

Distance

2 ( 1 − ϵ ) γ ⋅ n {\displaystyle 2(1-\epsilon )\gamma \cdot n}

Message length

n − m {\displaystyle n-m}

Notation

[ n , n − m , 2 ( 1 − ϵ ) γ ⋅ n ] 2 {\displaystyle [n,n-m,2(1-\epsilon )\gamma \cdot n]_{2}} -code

Rate

1 − m / n {\displaystyle 1-m/n}
