A bpalindrome is an integer that is a palindrome in base
b.
Show how to find a number that is a bpalindrome, of at least three digits, for at least 1000 different values of b.
For example, 200 is not a 10palindrome, but it is a 9palindrome (242) and a 7palindrome (404).

Oh, I see it's 1000 different values of b. Substitute 1000 for the 100 in my solution.
If both my solution and Brian Smith's withstand scrutiny (it does get a little confusing keeping track of those powers of 2), 2^(2^1001) is smaller than 2^(1002!), as 2^1001 is a 302digit number and 1002! is a 2,574digit number.
