 A195144 Reversal of n equals the sum of the reversals of the anti-divisors of n. 2
 5, 8, 895799 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS Like A069942 but using anti-divisors. No other terms up to 3*10^10. LINKS EXAMPLE The first two terms are banal cases: anti-divisors of 5 are 2 and 3 and their reversals are again 5, 2 and 3 and 2+3 = 5. The same for 8: 3+5 = 8. Anti-divisors of 895799 are 2, 3, 199, 597, 3001, 9003, 597199 and 2+3+991+795+1003+3009+991795 = 997598. MAPLE Rev:=proc(n) local a, i, k;   i:=convert(n, base, 10); a:=0;   for k from 1 to nops(i) do a:=a*10+i[k]; od;   a; end: P:=proc(j) local h, m, n, r; for m from 3 to j  do   h:=0;   for r from 2 to m-1 do     if abs((m mod r)-r/2)<1 then h:=h+Rev(r); print(r); fi;   od;   if h=Rev(m) then print(m); fi; od; end: P(1000000); CROSSREFS Cf.
