I found four candidates, (the four digit numbers being
1197,2403,4257,6903). What am I missing? Last fiddled with by davieddy on 20070320 at 09:46

Maybe by "consecutive" he meant distinct.

I did find the same candidates, but changing the problem to 3 consecutive squares I get 5555 = 41^2+43^2+45^2

That's quite a coincidence.
Must be what he meant. Well spotted! Last fiddled with by davieddy on 20070320 at 16:52

Mea culpa. I did mean three consecutive odd squares.
There's something to be said for repeating a preview before posting. And on such a simply stated problem. Last fiddled with by davar55 on 20070320 at 17:48
