Yes, sorry Ed -- 1001 can't be a candidate -- 
I'll rephrase asap!
Thanks,

Eric,

You weren't clear about this, but do you mean something more like: "A W
number is an integer W with the property that every digit d_k of W is a sum
of two or more distinct digits of W with indices different from k?"

Otherwise 1001 would be a candidate, wouldn't it?

Regards,

Ed Jeffery
