COMMENTS
Starting from n=5, a(n)=A277056(10)=92115, and the corresponding pandigitals are 1023499...989765 (n-5 nines).
a(1)-a(5) constitute row 10 of A277055.
a(n)*A002275(n) is 1023456789, 1024375869, 1023654987, 1234086579, 1023489765, ...

EXAMPLE
a(2) = 93125079 because A002275(2)*93125079 = 11*93125079 = 1024375869 that is a pandigital and 93125079 is the least number with this property.
