Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS").

EXAMPLE

2152 and 2512 are both multiples of 8.

MAPLE

revdigs:= proc(n) local L;

  L:= convert(n, base, 10);

  add(L[-i]*10^(i-1), i=1..nops(L))

end proc:

filter:= proc(n) local v;

  v:= revdigs(n);

  v <> n and v mod 8 = 0

end proc:

select(filter, [seq(i, i=8..5000, 8)]); # Robert Israel, Feb 24 2020

PROG

(ARIBAS): n := 8; stop := 4500; m := 0; while m < stop do rev := int_reverse(m); if m <> rev and rev mod n = 0 then write(m, " "); end; inc(m, n); end; .
