Just for fun


   - a(n) = Smallest number greater than n such the amount of letters of his
   name without spaces in English is a multiple of n


2, 4, 6, 5, 7, 11, 15, 13, 17, 24, 23, 73, 101, 104, 103, 111, 115, 113,
117, 124, 123, 173, 323, 373, 1104, 1103, 1111, 1115, 1113, 1117, 1124,
1123, 1173, 1323, 1373, 2373, 3323, 3373, 11373, 13323, 13373, 17373, 23323,
23373, 73373, 101373, 103323, 103373, 111373, 113323, 113373, 117373,
123323, 123373, 173373, 323373, 373373

All the terms > a(32) ends in 3?
Are there numbers that appear more than once?

In Spanish:

2, 3, 4, 6, 7, 15, 14, 40, 16, 17, 25, 24, 35, 34, 44, 54, 125, 124, 135,

2444, 2454, 3454, 4444, 4454, 14454, 16444

Apparently all the terms greater than a(20) ends in 4
