Compound of three octahedra

 * ... that the central chameleon cage in M. C. Escher's 1948 woodcut Stars has the shape of a compound of three octahedra (pictured)?
 * Reviewed: George Tchobanoglous
 * Comment: Relatedly, Stars has also been expanded. The expansion is less than 5x its previous maximum but is more than 5x if one measures from this version, which removed a copyvio from an earlier version. If this counts as a sufficient expansion, the title can also be bolded in the hook.

 * Symbol confirmed.svg Date, length, image and hook fine. I could find no copyvios or close paraphrasing. I have added an inline citation for the hook sentence.
 * I have bolded "Stars" in the hook as I believe it qualifies for inclusion under the 5x expansion rule. Cwmhiraeth (talk) 06:42, 2 December 2011 (UTC)
 * Unfortunately, the Stars article doesn't qualify as a 5x expansion, as calculated using DYKcheck and related tools. I unbolded it. --Orlady (talk) 20:05, 2 December 2011 (UTC)
 * Symbol confirmed.svg My mistake. If I measure from the David Eppstein's second edit (which is the one after he removed the copyvio), the expansion of Stars qualifies as 5x. --Orlady (talk) 22:26, 2 December 2011 (UTC)
