A perfect number is equal to the sum of its proper positive divisors.
A mirror perfect number is equal to the sum of its proper positive divisors when they are read backwards.
From a paper by Joseph L. Pe which is available on the 'net:
10311 = 1 + 3 + 7 + 21 + 491 + 1473 + 3437
7343 + 3741 + 194 + 12 + 7 + 3 + 1 = 11301
10311 is perfect and mirror perfect.
