CWW: "The next term after 62227496 that doesn't contain a 0 in the product is 6886826188 with the product being 97488368868261888."

When Eric suggested that his "gems" subsequence have images/products not containing any zeros, I thought he was being unduly restrictive. Ignoring products whose *final digit* is not zero reproduces his list and catches additional gems such as 3691262781 -> 803691262781568.
