Math Error in Scientific American Math article

Look, I'm only doing this because it is 'so obvious'. In the August 2009 issue of Scientific American there was an article about some longstanding unsolved problem in topology having been solved. The intro paragraph said:

Relax. Until recently, lurking in the dark recesses of mathematical existence, there might have been a really weird sphere of 254 dimensions, or 510, or 1,026. In fact, for all you knew, you might have had to worry about weird spheres when visiting any space with numbers of dimensions of the type 2^k - 2.

Any thing strike you here? 2^10-2 = 1022, not 1026. Easy mistake to make. Doing a calc of a sequence in your head, plus or minus one error. But fercrissakes...it's a math article. The only reason I bother to post this is because I can't find a record of it any where on the web (with a simple google search). I hold Scientific American in the highest regard. I can't seem to find a 'corrections' page though. Obligatory relevant link: Mathematicians celebrate baffling new proof
