there are 10 palindromic numbers between 9000 and 10000 9009,9119,9229,9339,9449,9559,9669,9779,9889,9999
8 digits will generate over 40,000 permutations.
89999 Any whole number above 99999 has 6 or more digits, and any whole number below 10000 has 4 or less digits. Since there are only whole numbers involved, it is a simple subtraction of 10000 from 99999.
Oh, dude, palindromic numbers are like those cool numbers that read the same forwards and backwards, right? So, between 1000 and 10000, you've got numbers like 1001, 1111, 1221... and so on. There are like 90 of them in total. So, like, that's your answer.
