Some pages with lots of numeric ref names (regex match: name=":\d+") possibly useful for analysis of numeric ref name usage by VE:
 * List of railway stations in Melbourne – 458 occurrences; only :0, :1, :2, and :5 are unique; all others are at least doubled, and go up to :228
 * Celebrity Big Brother (British series 12) – only 25, mostly single digits or teens/twenties, but include :175, :402, :975, and :2000.
 * List of Charadriiformes by population – 982 occurrences, highest is :256
