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; .
