Note from the image at right that if a 7×7×7 were to be constructed with layers of identical thickness the corner pieces (shown in red) would lose contact with the rest of the puzzle when a side was rotated 45 degrees.
Catatan dari gambar di sebelah kanan bahwa jika 7 × 7 × 7 itu harus dibangun dengan lapisan ketebalan identik potongan sudut (ditampilkan dalam warna merah) akan kehilangan kontak dengan sisa dari teka-teki ketika sisi itu diputar 45 derajat.
