2Authored explanation
Index coordinates by \(i=0,\ldots,11\) and encode \(x\in\{0,1\}^{12}\) as \(\iota(x)=\sum_i2^i x_i\). The witness is \[ A_L=\{x:0\leq\iota(x)<794\}. \] Equivalently, its 4,096-bit characteristic integer is \(B_L=2^{794}-1\), where bit \(j\) records membership of the vertex with integer label \(j\). Its canonical 512-byte little-endian encoding has SHA-256 digest \[ \texttt{4f55e719c472514a6f2b2e657127780a0740471a7038205203f403f17988ba8a}. \] Direct ordered-pair summation and an independent Walsh transform both give \[ E(A_L)=6{,}456{,}734{,}424. \] The family is also the disjoint union of binary subcubes corresponding to \(794=512+256+16+8+2\). Coordinate permutations and coordinate complements preserve the objective, so the full cube-automorphism orbit of this family gives witnesses with the same value.
