Even Wikipedia has it comfortably beaten:

6,895,000+ articles + 1,433,000+ 記事 + 2 004 000+ статей + 1.983.000+ artículos + 2.950.000+ Artikel + 2 641 000+ articles + 1,446,000+ 条目 / 條目 + 1.886.000+ voci + ۱٬۰۱۵٬۰۰۰+ مقاله + 1.134.000+ artigos = 23387000 > 16^6 = 0xffffff+1

6^16 != 16^6

Of course, but the number of subpages is actually 16^6 since the colours go from 0x000000 to 0xffffff; see the many other comments about that, including mine.
