A Twisted Perspective

Twelve reconstructed 3×3 cubes, shown in the installation coordinate frame. Inspect one, orbit the complete fixed arrangement, or compare all twelve unfolded nets.

Face evidence

Completeness and evidence type are separate: every cube is complete, while some hidden faces are reconstructed rather than directly seen.

U Reconciled
Teammate transcription, checked against centers and overlapping photographs but not independently reread sticker-by-sticker.
L Reconciled
Teammate transcription, checked against centers and overlapping photographs but not independently reread sticker-by-sticker.
Front Photographed
Read directly from one or more supplied photographs.
R Photographed
Read directly from one or more supplied photographs.
Rear Photographed
Read directly from one or more supplied photographs.
D Photographed
Read directly from one or more supplied photographs.
Coordinates and provenance

Data snapshot: problem-5/derived/face-transcription.json, schema version 1, updated 2026-08-08. Cube IDs use Crc: row 1 is the top row, row 3 is the bottom row, and columns run installation-left to right.

  • U: rear-to-front, left-to-right.
  • D: front-to-rear, left-to-right.
  • L: up-to-down, rear-to-front from outside.
  • Front: up-to-down, left-to-right.
  • R: up-to-down, front-to-rear from outside.
  • Rear: up-to-down, installation-right to left from outside.

Front, right, and Rear faces were independently read from the supplied photographs. The new high-resolution rear-side set confirms all 108 previously legality-forced Rear stickers without a discrepancy. Some U/L faces retain the teammate transcription after cross-view reconciliation. D faces C22–C34 come from a teammate bottom-face transcription whose 53 previously recorded sticker cells all matched existing evidence.

Across all twelve cubes, the evidence ledger covers 423 directly photographed stickers, 153 reconciled U/L stickers, 63 teammate D-face stickers, and 9 C21 photo-patch/legal D stickers. All 648 literal stickers are known and every literal six-face layout is unique.
