37 is peculiar because many of its multiples (like 111, 222, 333, etc.) show perfect numerical symmetry, and the sum of the digits of its multiples is always a multiple of 3.
For example:
37 × 3 = 111
37 × 6 = 222
37 × 9 = 333…
It’s the only two-digit number that shows this exact pattern with multiples of 3 and repeating digits.
