EXAMPLE
264 and 462 are non-palindromic and also d(264) = 16 = d(462), and so both are members.
PROG
(PARI) isok(k) = my(R = fromdigits(Vecrev(digits(k)))); R != k && numdiv(R) == numdiv(k);
(Python)
from sympy import divisor_count as d
def ok(k): Rk = int(str(k)[::-1]); return Rk != k and d(k) == d(Rk)
print([k for k in range(320) if ok(k)]) # Michael S. Branicky, Feb 20 2022
