No; 20 is an abundant number.
S = {1, 2, 4, 5, 10} is the set of all positive divisors of 20, excluding itself.
The sum of these divisors = 1+2+4+5+10=22 which is greater than 20.
Therefore 20 is an abundant number, not a deficient number.
When the sum exceeds the number, the number is abundant.
When the sum equals the number, the number is perfect.
When the sum is less than the number, the number is deficient.

Is 34 an abundant perfect or a deficient number?
To find out if a number is abundant, perfect or deficient, you first need to split it into its prime factors: 34 = 2x17 The next step would be to find any combinations, but as we have only 2 prime factors, those are the two we'll work with. You add these together, with 1, and get 20. When this sums to less than the original number it's a deficient number. 20 is less than 34, and so 34 is a deficient number.
