The Wild Numbers

[N. J. A. Sloane]

"Science" for Dec 22 2001 has a review of a book called The Wild Numbers
by P. Schogt. Apparently the sequence of wild numbers begins:
a(0)=11, a(1)=67, a(2)=2, a(3)=4769, a(4)=67.

I am tentatively adding it to the EIS as A058883:

%I A058883
%S A058883 11,67,2,4769,67
%N A058883 Wild numbers.
%C A058883 I learned about these from the review in Science; but how are they defined?
%D A058883 P. Schogt, The Wild Numbers, Four Walls Eight Windows Pub., New York, 2000.
%D A058883 D. F. Wallace, Rhetoric and the math melodrama, Science, 290 (22 Dec. 2000), 2263-2267.
%D A058883 A number of further reviews of this book exist on the Web.
%H A058883 <a href="http://www.complete-review.com/reviews/maths/schogtp.htm">Another review</a>
%O A058883 0,1
%K A058883 nonn,obsc 
%A A058883 njas, Jan 08 2001

Does anyone know how they are defined?
