An Oddly-Abundant Number

An Abundant Number is one for which the sum of its proper divisors is greater than the number itself. The proper divisors are those integers which divide into the number, which includes 1 but excludes the number itself.

Example: 12's proper divisors are 1, 2, 3, 4, 6. These add up to 16, which is greater than 12, so 12 is Abundant.

Find an odd Abundant Number, which is also palindromic, and which is less than 10000.
