Fortunately, a simple workaround via sums of Stirling numbers

grinds to a conclusion in a minute (G4 Macintosh).
Heigh-ho --- now for the inevitable correction --- should have read with(combinat); p := 521; q := 41; add(stirling2(p+1, i), i = 0..p+1) mod q; add(stirling2(q+1, i), i = 0..q+1) mod p; WFL
