Today I Learned that the number 69 is the only natural number whose square (4761) and cube (328509) contains every digit from 0 to 9 exactly once!

I know one more number that is a perfect number and contains not more than 2 digits. Find the number ?

According to number theory of mathematics , a perfect number is a positive integer that is equal to the sum of its positive divisors excluding the number itself.
For example :
6 => 1+2+3
28 =>1+2+4+7+14

Find the number ?
