Why is the International Olympic Committee Country Code for the Netherlands Antilles "AHO"?

Question

I was perplexed to see a country abbreviated "AHO" on the TV, so I looked it up, and found that it was the Netherlands Antilles. But that seems to have nothing to do with the country's spelling in English or Dutch. Does anyone know how the IOC arrived at this code?

Answer 1

The IOC code for the Netherlands Antilles is AHO.

Answer 2

Netherlands Antilles is also know as Antia Hulandes

Netherlands is also know as Holland

So I'd guess the AHO come from these variations
