ALL ANIMALS ARE EQUAL

A contrived simple
equivalence
rule applies neatly to numbers 0 through 99
but not to any other numbers.
Equivalences of numbers 0 through 19 are listed below,
accounting for almost all other eligible numbers as well,
where ‘=’ means “is equivalent to.”
(Each number is
reflexively
equivalent to itself.)
0 = no others
10 = no others
1 = no others
11 = 29 = 31 = 49 = 51 = 69 = 71 = 89 = 91
2 = no others
12 = 28 = 32 = 48 = 52 = 68 = 72 = 88 = 92
3 = no others
13 = 27 = 33 = 47 = 53 = 67 = 73 = 87 = 93

9 = no others
19 = 21 = 39 = 41 = 59 = 61 = 79 = 81 = 99
What would be the entry for 20 in this list?
20 = ___ . . . ?
Please use and explain the simplest possible rule,
not purely mathematical,
that accounts for every equivalence from 0 to 99.

Answer:
20 = no others
Reason: (humn has told me that this is wrong but it's my favorite guess of mine)
Because you gave us a list of equivalences which are more equal than others. So we can assume the remaining numbers are less equal and therefore only equal to themselves.
Other guesses:
Xilpex's rule applies if no digits are zero. If any digit is zero (
2can be written as02) then there are no equivalents
Because the rules are contrived so I can simply invent whatever I want for the rules that aren't given to me.

20 would be:

The rule (vertically) is: Line 1 + 1, then Line 2 - 1, and so on.

20 would be:
20 = 20 = 40 = 40 = 60 = 60 = 80 = 80 = 100
Explanation:
The rule (vertically) is: Line 1 + 1, then Line 2 - 1, and so on.

Delete the tens digit, like follow:

1 = no others 1 = 9 = 1 = 9 = 1 = 9 = 1 = 9 = 1
