A257914 Pandigital numbers reordered so that the numbers A050278(n)/(2^k*5^m), where 2^k||A050278(n) and 5^m||A050278(n), appear in nondecreasing order. 1

%N Pandigital numbers reordered so that the numbers A050278(n)/(2^k*5^m), where 2^k||A050278(n) and 5^m||A050278(n), appear in nondecreasing order.

%C If two such numbers A050278(n_1)/(2^k_1*5^m_1) and A050278(n_2)/(2^k_2*5^m_2) are equal, then A050278(n_1) appears earlier than A050278(n_2) iff A050278(n_1)<A050278(n_2). For example, a(8)/(2^0*5^8)=a(9)/(2^1*5^8)= 4671. There are 234710 such pairs.

%C Note that, a(1) = 3076521984 means that min(A050278(n)/(2^k*5^m)) = 3076521984/(2^21*5^0) = 1467.

%Y Cf. A050278, A257893, A257899, A257901, A257913.
