Any single digit number is a palindrome. The Fibonacci sequence consists of infinitely many numbers so 8, being only one number, cannot be the Fibonacci sequence.
You cannot make a palindrome with 3 different digits. You can only do that if you have a set of paired digits, and at most one single digit.
101 is the only palindromic number in the specified range.
only 1, 11
One. If you mean "digits", the number can have any amount of digits; the only requirement to be called a "palindrome" is that if you read it backwards, you get the same sequence of digits. Thus, any of the following is a palindrome: 1 (any 1-digit number is a palindrome), 55, 121, 2002, 12321, 600006, 8105018, ... As you can see, you can make them arbitrarily large.
