Robert Israel, Table of n, a(n) for n = 100..10000
EXAMPLE
a(112)=560 because 560 = 5*112 contains each of its digits once, while 112, 2*112=224, 3*112=336 and 4*112=448 do not have equal frequencies of their digits. - Robert Israel, Jun 08 2020

end proc:

for k from n by n do if filter(k) then return k fi od
