Actor John Cazale had a brief acting career, just 6 years. During those years appeared in 5 films; The Godfather, The Conversation, The Godfather Part II, Dog Day Afternoon, and The Deer Hunter. All 5 of these films were nominated for an Academy Award for Best Picture. After his death from lung cancer in 1978, archival footage of John Cazale was used in The Godfather Part III, also nominated for Best Picture.

Follow-up on my last post here: The smallest number palindromic of 16 digits in two different integer bases is decimal 530386561769238496 -- A49232022023294A in base 13 and 1327D169961D7231 in base 15. Assuming one exists, the smallest number palindromic of 18 digits in two different bases has smaller base of 18-digit palindromicity at least 20. [The problem for an odd number of digits is much easier.]

Hmmm. Guess I should have used lower case.

Ah, well, it looks like I quit just short in my search for a 2-fold 18-palindrome a while back. Decimal 73012066376764835227425 is an 18-digit palindrome in bases 20 and 22. The smallest, if my earlier program wasn't faulty, and I've no reason to suspect it was. The base-20 and -22 representations: 5B830BA7227AB038B5 and 1258I9FJ77JF9I8521.

Probably correct, but it's a hasty declaration. My programming hasn't rule out smaller numbers yet, just bases under 20.

Well, on 3rd thought, since the smallest 18-digit base-23 number is bigger than this, the number is obviously the smallest of the kind.

Heh... A few days ago I heard someone on the radio point out the "interesting fact" that a group of cats is called a "clowder" and I instantly thought to myself, "No, they're called a bunch of cats", like nearly every other group of animals.
